ONBOARD FLASH Support + +FLASH support is provided for the onboard FLASH chip Bootrom area. +U-Boot is loaded into either the ROM boot region of the FLASH chip, +after first being boot-strapped from a pre-progammed AMD29F040 PLCC +bootrom. The PLCC needs to be programmed with a ROM burner using +AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record) +images. + +The PLCC overlays this same region of flash as the onboard FLASH, +the jumper J100 is a chip-select for which flash chip you want to +progam. When jumper J100 is connected to pins 2-3, you boot from +PLCC FLASH. + +To bringup a system, simply flash a flash an AMD29F040 PLCC +bootrom, and put this in the PLCC socket. Move jumper J100 to +pins 2-3 and boot from the PLCC. + + +Now, while the system is running, move Jumper J100 to +pins 1-2 and follow the procedure below to FLASH a bootrom +(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB): + +tftp 100000 u-boot.bin +protect off FFF00000 FFF7FFFF +erase FFF00000 FFF7FFFF +cp.b 100000 FFF00000 \$(filesize)\ + + +Here is an example: + +=>tftp 100000 u-boot.bin +eth_halt +eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0) +DEC Ethernet iobase=0x80000000 +ARP broadcast 1 +Filename 'u-boot.bin'. +Load address: 0x100000 +Loading: ######################### +done +Bytes transferred = 123220 (1e154 hex) +eth_halt +=>protect off FFF00000 FFF7FFFF +Un-Protected 8 sectors +=>erase FFF00000 FFF7FFFF +Erase Flash from 0xfff00000 to 0xfff7ffff +Erase FLASH[PLCC_BOOT] -8 sectors:........ done +Erased 8 sectors +=>cp.b 100000 FFF00000 1e154 +Copy to Flash...

SDRAM module. + + +Changes: +======== + +Added Devices: +============== + +Floppy support: +--------------- +Support of a standard floppy disk controller at address CFG_ISA_IO_BASE_ADDRESS ++ 0x3F0. Enabled with define CFG_CMD_FDC. Reads a unformated floppy disk with a +image header (see: mkimage). No interrupts and no DMA are used for this. +Added files: +- common/cmd_fdc.c +- include/cmd_fdc.h + +SCSI support: +------------- +Support for Symbios SYM53C810A chip. Implemented as follows: +- without disconnect +- only asynchrounous +- multiple LUN support (caution, needs a lot of RAM. define CFG_SCSI_MAX_LUN 1 to + save RAM) +- multiple SCSI ID support +- no write support +- analyses the MAC, DOS and ISO pratition similar to the IDE support +- allows booting from SCSI devices similar to the IDE support. +The device numbers are not assigned like they are within the IDE support. The first +device found will get the number 0, the next 1 etc. If all SCSI IDs (0..6) and all +LUNs (8) are enabled, 56 boot devices are possible. This uses a lot of RAM since the +device descriptors are not yet dynamically allocated. 56 boot devices are overkill +anyway. Please refer to the section "Todo" chapter "block device support enhancement". +The SYM53C810A uses 1 Interrupt and must be able of mastering the PCI bus. +Added files: +- common/cmd_scsi.c +- common/board.c +- include/cmd_scsi.h +- include/scsi.h +- board/pip405/sym53c8xx.c +- board/pip405/sym53c8xx_defs.h + +ATAPI support (IDE changes): +---------------------------- +Added ATAPI support (with CONFIG_ATAPI) in the file cmd_ide.c. +To support a hardreset, when the IDE reset pin is not connected to the +CFG_PC_IDE_RESET pin, the switch CONFIG_IDE_RESET_ROUTINE has been added. When +this switch is enabled the routine void ide_set_reset(int idereset) must be +within the board specific files. +Only read from ATAPI devices are supported. +Found out that the function trim_trail cuts off the last character if the whole +string is filled. Added function cpy_ident instead, which trims also leading +spaces and copies the string in the buffer. +Changed files: +- common/cmd_ide.c +- include/ata.h + +ISO partition support: +---------------------- +Added CD boot support for El-Torito bootable ISO CDs. The bootfile image must contain +the U-Boot image header. Since CDs do not have "partitions", the boot partition is 0. +The bootcatalog feature has not been tested so far. CD Boot is supported for ATAPI +("diskboot") and SCSI ("scsiboot") devices. +Added files: +- disk/iso_part.c +- disk/iso_part.h + +Block device changes: +--------------------- +To allow the use of dos_part.c, mac_part.c and iso_part.c, the parameter +block_dev_desc will be used when accessing the functions in these files. The block +device descriptor (block_dev_desc) contains a pointer to the read routine of the +device, which will be used to read blocks from the device. +Renamed function ide_print to dev_print and moved it to the file disk/part.c to use +it for IDE ATAPI and SCSI devices. +Please refer to the section "Todo" chapter "block device support enhancement". +Added files: +- include/part.h +changed files: +- disk/dos_part.c +- disk/dos_part.h +- disk/mac_part.c +- disk/mac_part.h +- disk/part.c +- common/cmd_ide.c +- include/u-boot.h + + +MC146818 RTC support: +--------------------- +Added support for MC146818 RTC with defining CONFIG_RTC_MC146818. The ISA bus IO +base address must be defined with CFG_ISA_IO_BASE_ADDRESS. +Added files: +- rtc/mc146818.c + +Standard ISA bus Keyboard support: +---------------------------------- +Added support for the standard PC kyeboard controller. For the PIP405 the superIO +controller must be set up previously. The keyboard uses the standard ISA IRQ, so +the ISA PIC must also be set up. +Added files: +- board/pip405/kbd.c +- board/pip405/kbd.h +- board/pip405/pip405_isa.c +- board/pip405/pip405_isa.h + +Chips and Technologie 69000 VGA controller support: +--------------------------------------------------- +Added support for the CT69000 VGA controller. +Added files: +- board/pip405/video.c +- board/pip405/video.h +- board/pip405/vga_table.h + + +Changed Items: +============== + +Identify: +--------- +Added the config variable CONFIG_IDENT_STRING which will be added to the +"U_BOOT_VERSION __TIME__ DATE___ " String, to allows to identify intermidiate +and custom versions. +Changed files: +- cpu/ppc4xx/start.s + +Firmware Image: +--------------- +Added IH_OS_U_BOOT and IH_TYPE_FIRMWARE to the image definitions to allows the +U-Boot update with prior CRC check. +Changed files: +- include/image.h +- tools/mkimage.c +- common/cmd_bootm.c + +Correct PCI Frequency for PPC405: +--------------------------------- +Added function (in cpu/ppc4xx/speed.c) to get the PCI frequency for PPC405 CPU. +The PCI Frequency will now be set correct in the board description in common/board.c. +(was set to the busfreq before). +Changed files: +- cpu/ppc4xx/speed.c +- common/board.c + +I2C Stuff: +---------- +Added defined(CONFIG_PIP405) at several points in common/cmd_i2c.c. +Added 16bit read/write support for I2C (PPC405), and page write to +I2C EEPROM if defined CFG_EEPROM_PAGE_WRITE_ENABLE. +Changed files: +- cpu/ppc4xx/i2c.c +- common/cmd_i2c.c + +Environment / Console: +---------------------- +Although in README.console described, the U-Boot has not assinged the values +found in the environment to the console. Corrected this behavior, but only if +CFG_CONSOLE_IS_IN_ENV is defined. +If CFG_CONSOLE_OVERWRITE_ROUTINE is defined, console_overwrite() decides if the +values stored in the environment or the standard serial in/output should be +assigned to the console. This is useful if the environment values are not correct. +If CFG_CONSOLE_ENV_OVERWRITE is defined the devices assigned to the console at +start-up time will be written to the environment. This means that if the +environment values are overwritten by the overwrite_console() routine, they will be +stored in the environment. +Changed files: +- common/console.c + +Correct bootdelay intepretation: +-------------------------------- +Changed bootdelay read from the environment from simple_strtoul (unsigned) to +simple_strtol (signed), to be able to get a bootdelay of -1. +Changed files: +- common/main.c + +Todo: +===== + +Block device support enhancement: +--------------------------------- +Consider to unify the block device handling. Instead of using diskboot for IDE, +scsiboot for SCSI and fdcboot for floppy disks, it would make sense to use only +one command ("devboot" ???) with a parameter of the desired device ("hda1", "sda1", +"fd0" ???) to boot from. The other ide commands can be handled in the same way +("dev hda read.." instead of "ide read.." or "dev sda read.." instead of +"scsi read..."). Todo this, a common way of assign a block device to its name +(first found ide device = hda, second found hdb etc., or hda is device 0 on bus 0, +hdb is device 1 on bus 0 etc.) as well as the names (hdx for ide, sdx for scsi, fx for +floppy ???) must be defined. +Maybe there are better ideas to do this. + +Console assingment: +------------------- +Consider to initialize and assign the console stdin, stdout and stderr as soon as +possible to see the boot messages also on an other console than serial. + + +Todo for PIP405: +================ + +LCD support for VGA: +-------------------- +Add LCD support for the CT69000 + +Default environment: +-------------------- +Consider to write a default environment to the OTP part of the EEPROM and use it +if the normal environment is not valid. Useful for serial# and ethaddr values. + +Watchdog: +--------- +Implement Watchdog. + +Files clean-up: +--------------- +Following files needs to be cleaned up: +- cmd_pip405.c +- flash.c +- pci_pip405.c +- pip405.c +- pip405_isa.c +Consider to split up the files in their functions. diff --git a/doc/README.RPXlite b/doc/README.RPXlite new file mode 100644 index 0000000000..25bf80b2a8 --- /dev/null +++ b/doc/README.RPXlite @@ -0,0 +1,887 @@ +# Porting U-Boot onto RPXlite board +# Written by Yoo.

It will need *extensive* hacking to modify it to keep the +information about your custom boards that you want, however it is a good +starting point. + +How it is used: + + 1. a board has gone through all the hardware testing etc and is + ready to have the flash programmed for the first time - first you + go to a web page and fill in information about the board in a form + to register it in a database + + 2. the web stuff allocates a (unique) serial number and (optionally) + a (locally administered) ethernet address and stores the information + in a database using the serial number as the key (can do whole + batches of boards in one go and/or use a previously registered board + as defaults for the new board(s)) + + 3. it then creates a file in the tftp area of a server somewhere + containing the board information in a simple text format (one + per serial number) + + 4. all hymod boards have an i2c eeprom, and when U-Boot sees that + the eeprom is unitialised, it prompts for a serial number and + ethernet address (if not set), then transfers the file created + in step 3 from the server and initialises the eeprom from its + contents + +What this means is you can't boot the board until you have allocated a serial +number, but you don't have to type it all twice - you do it once on the web +and the board then finds the info it needs to initialise its eeprom. The +other side of the coin is the reading of the eeprom and how it gets passed +to Linux (or another O/S). + +To see how this is all done for the hymod boards look at the code in the +"board/hymod" directory and in the file "include/asm/hymod.h". Hymod boards +can have a mezzanine card which also have an eeprom that needs allocating, +the same process is used for these as well - just a different i2c address. + +Other forms provide the following functions: + + - browsing the board database + - editing board information (one at a time) + - maintaining/browsing a (simple) per board event log + +You will need: MySQL (I use version 3.23.7-alpha), PHP4 (with MySQL +support enabled) and a web server (I use Apache 1.3.x). + +I originally started by using phpMyBuilder (http://kyber.dk/phpMyBuilder) +but it soon got far more complicated than that could handle (but I left +the copyright messages in there anyway). Most of the code resides in the +common defs.php file, which shouldn't need much alteration - all the work +will be in shaping the front-end php files to your liking. + +Here's a quick summary of what needs doing to use it for your boards: + +1. get phpMyAdmin (http://phpwizard.net/projects/phpMyAdmin/) - it's an + invaluable tool for this sort of stuff (this step is optional of course) + +2. edit "bddb.css" to your taste, if you could be bothered - I have no + idea what is in there or what it does - I copied it from somewhere else + ("user.css" from the phpMyEdit (http://phpmyedit.sourcerforge.net) package, + I think) - I figure one day I'll see what sort of things I can change + in there. + +3. create a mysql database - call it whatever you like + +4. edit "create_tables.sql" and modify the "boards" table schema to + reflect the information you want to keep about your boards. It may or + may not be easier to do this and the next step in phpMyAdmin. Check out + the MySQL documentation at http://www.mysql.com/doc/ in particular the + column types at http://www.mysql.com/doc/C/o/Column_types.html - Note + there is only support for a few data types: + + int - presented as an html text input + char/text - presented as an html text input + date - presented as an html text input + enum - presented as an html radio input + + I also have what I call "enum_multi" which is a set of enums with the + same name, but suffixed with a number e.g. fred0, fred1, fred2. These + are presented as a number of html select's with a single label "fred" + this is useful for board characteristics that have multiple items of + the same type e.g. multiple banks of sdram. + +5. use the "create_tables.sql" file to create the "boards" table in the + database e.g. mysql dbname < create_tables.sql + +6. create a user and password for the web server to log into the MySQL + database with; give this user select, insert and update privileges + to the database created in 3 (and delete, if you want the "delete" + functions in the edit forms to work- I have this turned off). phpMyAdmin + helps in this step. + +7. edit "config.php" and set the variables: $mysql_user, $mysql_pw, $mysql_db, + $bddb_cfgdir and $bddb_label - keep the contents of this file secret - it + contains the web servers username and password (the three $mysql_* vars + are set from the previous step) + +8. edit "defs.php" and a. adjust the various enum value arrays and b. edit + the function "pg_foot()" to remove my email address :-) + +9. do major hacking on the following files: browse.php, doedit.php, donew.php, + edit.php and new.php to reflect your database schema - fortunately the + hacking is fairly straight-forward, but it is boring and time-consuming. + +These notes were written rather hastily - if you find any obvious problems +please let me know. diff --git a/tools/bddb/brlog.php b/tools/bddb/brlog.php new file mode 100644 index 0000000000..6e98c9c481 --- /dev/null +++ b/tools/bddb/brlog.php @@ -0,0 +1,106 @@ +<?php // php pages made with phpMyBuilder <http://kyber.dk/phpMyBuilder> ?> +<?php + // (C) Copyright 2001 + // Murray Jensen <Murray.Jensen@cmst.csiro.au> + // CSIRO Manufacturing Science and Technology, Preston Lab + + // list page (hymod_bddb / boards) + + require("defs.php"); + + pg_head("$bddb_label - Browse Board Log"); + + if (!isset($serno) || $serno == 0) + die("serial number not specified!"); + + function print_cell($str) { + if ($str == '') + $str = ' '; + echo "\t<td>$str</td>\n"; + } +?> +<table align=center border=1 cellpadding=10> +<tr> +<th>serno / edit</th> +<th>ethaddr</th> +<th>date</th> +<th>batch</th> +<th>type</th> +<th>rev</th> +<th>location</th> +</tr> +<?php + $r=mysql_query("select * from boards where serno=$serno"); + + while($row=mysql_fetch_array($r)){ + foreach ($columns as $key) { + if (!key_in_array($key, $row)) + $row[$key] = ''; + } + + echo "<tr>\n"; + print_cell("<a href=\"edit.php?serno=$row[serno]\">$row[serno]</a>"); + print_cell($row['ethaddr']); + print_cell($row['date']); + print_cell($row['batch']); + print_cell($row['type']); + print_cell($row['rev']); + print_cell($row['location']); + echo "</tr>\n"; + } + + mysql_free_result($r); +?> +</table> +<hr></hr> +<p></p> +<?php + $limit=abs(isset($limit)?$limit:20); + $offset=abs(isset($offset)?$offset:0); + $lr=mysql_query("select count(*) as n from log where serno=$serno"); + $lrow=mysql_fetch_array($lr); + if($lrow['n']>$limit){ + $preoffset=max(0,$offset-$limit); + $postoffset=$offset+$limit; + echo "<table width=\"100%\">\n<tr align=center>\n"; + printf("<td><%sa href=\"%s?serno=$serno&offset=%d\"><img border=0 alt=\"<\" src=\"/icons/left.gif\"></a></td>\n", $offset>0?"":"no", $PHP_SELF, $preoffset); + printf("<td><%sa href=\"%s?serno=$serno&offset=%d\"><img border=0 alt=\">\" src=\"/icons/right.gif\"></a></td>\n", $postoffset<$lrow['n']?"":"no", $PHP_SELF, $postoffset); + echo "</tr>\n</table>\n"; + } + mysql_free_result($lr); +?> +<table width="100%" border=1 cellpadding=10> +<tr valign=top> +<th>logno / edit</th> +<th>date</th> +<th width="70%">details</th> +</tr> +<?php + $r=mysql_query("select * from log where serno=$serno order by logno limit $offset,$limit"); + + while($row=mysql_fetch_array($r)){ + echo "<tr>\n"; + print_cell("<a href=\"edlog.php?serno=$row[serno]&logno=$row[logno]\">$row[logno]</a>"); + print_cell($row['date']); + print_cell("<pre>" . urldecode($row['details']) .
