2017-08-11Kconfig: Drop CONFIG_CMD_PORTIO and associated commandSimon Glass1-5/+4
This command is not used by any board. It also looks quite similar to the 'iod' and 'iow' commands which use the correct I/O macros. Drop it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
2016-04-01Drop command-processing code when CONFIG_CMDLINE is disabledSimon Glass1-0/+18
Command parsing and processing code is not needed when the command line is disabled. Remove this code in that case. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2016-03-22Allow command code to compile to nothingSimon Glass1-4/+27
When CONFIG_CMDLINE is disabled we need to remove all the command-line code. Most can be removed by dropping the appropriate linker lists from the images, but sub-commands must be dealt with specially. A simple mechanism is used to avoid 'unused static function' errors.

2015-12-07CONFIG_NEEDS_MANUAL_RELOC: Fix warnings when not setTom Rini1-4/+1
Now that we may compile (but not link) code calling fixup_cmdtable when this is not set, we need to always have the declaration available. We should also make sure that anyone calling the function includes <command.h> as that's where the function declaration is. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-07-27pxe: add AArch64 image supportStephen Warren1-0/+2
The sysboot and pxe commands currently support either U-Boot formats or raw zImages. Add support for the AArch64 Linux port's native image format too. As with zImage support, there is no auto-detection of the native image format. Rather, if the image is auto-detected as a U-Boot format, U-Boot will try to interpret it as such. Otherwise, U-Boot will fall back to a raw/native image format, if one is enabled. My belief is that CONFIG_CMD_BOOTZ won't ever be enabled for any AArch64 port, hence there's never a need to differentiate between CONFIG_CMD_ _BOOTI and _BOOTZ at run-time; compile-time will do. Even if this isn't true, we want to prefer _BOOTI over _BOOTZ when defined, since _BOOTI is definitely the native format for AArch64.

2014-10-27cli: hush: Adjust 'run' command to run each line of the env varSimon Glass1-0/+1
The run command treats each argument an an environment variable. It gets the value of each variable and executes it as a command. If an environment variable contains a newline and the hush cli is used, it is supposed to execute each line one after the other. Normally a newline signals to hush to exit - this is used in normal command line entry - after a command is entered we want to return to allow the user to enter the next one. But environment variables obviously need to execute to completion. Add a special case for the execution of environment variables which continues when a newline is seen, and add a few tests to check this behaviour. Note: it's not impossible that this may cause regressions in other areas. I can't think of a case but with any change of behaviour with limited test coverage there is always a risk. From what I can tell this behaviour has been around since at least U-Boot 2011.03, although this pre-dates sandbox and I have not tested it on real hardware.

2014-03-04Add cmd_process_error() to report and process errorsSimon Glass1-0/+9
U-Boot now uses errors defined in include/errno.h which are negative integers. Commands which fail need to report the error and return 1 to indicate failure. Add this functionality in cmd_process_error(). For now this merely reports the error number. It would be possible also to produce a helpful error message by storing the error strings in U-Boot.

2013-03-12Refactor linker-generated arraysAlbert ARIBAUD1-1/+1
Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

2012-10-22common: Discard the __u_boot_cmd sectionMarek Vasut1-2/+0
The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed.

2012-10-22common: Convert the U-Boot commands to LG-arraysMarek Vasut1-12/+14
This patch converts the old method of creating a list of command onto the new LG-arrays code. The old u_boot_cmd section is converted to new u_boot_list_cmd subsection and LG-array macros used as needed. Minor adjustments had to be made to the common code to work with the LG-array macros, mostly the fixup_cmdtable() calls are now passed the ll_entry_start and ll_entry_count instead of linker-generated symbols. The command.c had to be adjusted as well so it would use the newly introduced LG-array API instead of directly using linker-generated symbols.

We currently have the same code in hush.c and main.c. This brings the code into one place. As an added feature, if the command function returns CMD_RET_USAGE then cmd_process() will print a usage message for the command before returning the standard failure code of 1.

2011-10-17sandbox: Force command sections to be 4-byte alignedSimon Glass1-1/+2
By default sections are 16-byte aligned on some architectures, but the command name structure (struct cmd_tbl_s) does not have padding to 16 bytes. This reduces the alignment to 4-bytes so that the command table can be accessed correctly on any architecture. (Note: this needs doing properly) Signed-off-by: Simon Glass <sjg@chromium.org>

2010-11-28autocomplete: remove runtime handler installMike Frysinger1-12/+18
Rather than add runtime overhead of installing completion handlers, do it statically at build time. This requires a new build time helper macro to declare a command and the completion handler at the same time. Then we convert the env related funcs over to this.

2010-11-28command_t: punt unused typeMike Frysinger1-2/+0

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk1-4/+4
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

2009-06-12Make "usage" messages more helpful.Wolfgang Denk1-1/+1
In case of incorrect command invocations U-Boot used to print pretty useless "usage" messages, for example: => nand markbad Usage: nand - NAND sub-system In the result, the user would have to run the "help" command to get the (available) information about correct command usage. Change this, so that this information gets always printed. Note that this changes the user interface of all commands, but hopefully to the better. Signed-off-by: Wolfgang Denk <wd@denx.de>
