2010-05-19jffs2: Erase pending blocks in GC pass, avoid invalid -EIO returnDavid Woodhouse3-4/+30
jffs2_garbage_collect_pass() would previously return -EAGAIN if it couldn't find anything to garbage collect from, and there were blocks on the erase_pending_list. If the blocks were actually in the process of being erased, though, then they wouldn't be on that list. Check for nr_erasing_blocks being non-zero instead. Fix jffs2_reserve_space() to wait for the in-progress erases to complete, when jffs2_garbage_collect_pass() returns -EAGAIN. And fix jffs2_erase_succeeded() to actually wake up the erase_wait wq that jffs2_reserve_space() is now using. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2010-05-14mtd: nand: support alternate BB marker locations on MLCKevin Cernekee3-0/+20
This is a slightly modified version of a patch submitted last year by Reuben Dowle <reuben.dowle@navico.com>. His original comments follow: This patch adds support for some MLC NAND flashes that place the BB marker in the LAST page of the bad block rather than the FIRST page used for SLC NAND and other types of MLC nand. Lifted from Samsung datasheet for K9LG8G08U0A (1Gbyte MLC NAND): " Identifying Initial Invalid Block(s) All device locations are erased(FFh) except locations where the initial invalid block(s) information is written prior to shipping. The initial invalid block(s) status is defined by the 1st byte in the spare area. Samsung makes sure that the last page of every initial invalid block has non-FFh data at the column address of 2,048. ... " As far as I can tell, this is the same for all Samsung MLC nand, and in fact the samsung bsp for the processor used in our project (s3c6410) actually contained a hack similar to this patch but less portable to enable use of their NAND parts. I discovered this problem when trying to use a Micron NAND which does not used this layout - I wish samsung would put their stuff in main-line to avoid this type of problem. Currently this patch causes all MLC nand with manufacturer codes from Samsung and ST(Numonyx) to use this alternative location, since these are the manufactures that I know of that use this layout.

2010-05-14mtd: nand: extend NAND flash detection to new MLC chipsKevin Cernekee2-21/+45
Some of the newer MLC devices have a 6-byte ID sequence in which several field definitions differ from older chips in a manner that is not backward compatible. For instance: Samsung K9GAG08U0M (5-byte sequence): ec d5 14 b6 74 4th byte, bits 1:0 encode the page size: 0=1KiB, 1=2KiB, 2=4KiB, 3=8KiB 4th byte, bits 5:4 encode the block size: 0=64KiB, 1=128KiB, ... 4th byte, bit 6 encodes the OOB size: 0=8B/512B, 1=16B/512B Samsung K9GAG08U0D (6-byte sequence): ec d5 94 29 34 41 4th byte, bits 1:0 encode the page size: 0=2KiB, 1=4KiB, 3=8KiB, 4=rsvd 4th byte, bits 7;5:4 encode the block size: 0=128KiB, 1=256KiB, ... 4th byte, bits 6;3:2 encode the OOB size: 1=128B/page, 2=218B/page This patch uses the new 6-byte scheme if the following conditions are all true: 1) The ID code wraps around after exactly 6 bytes 2) Manufacturer is Samsung 3) 6th byte is zero The patch also extends the maximum OOB size from 128B to 256B.

2010-05-14mtd: sst25l: fix multi-part messages with broken spi mastersH Hartley Sweeten1-24/+33
Some SPI masters (ep93xx) have limitations when using the SFRMOUT signal for the spi device chip select. The SFRMOUT signal is only asserted as long as the spi transmit fifo contains data. As soon as the last bit is clocked into the receive fifo it gets deasserted. The functions sst25l_status and sst25l_match_device use the API function spi_write_then_read to write a command to the flash then read the response back. This API function creates a two part spi message for the write then read. When this message is transferred the SFRMOUT signal ends up getting deasserted after the command phase. This causes the command to get aborted by the device so the read phase returns invalid data. By changing sst25l_status and sst25l_match_device to use a single transfer synchronous message, the SFRMOUT signal stays asserted during the entire message so the correct data always gets returned. This change will have no effect on SPI masters which use a chip select mechanism (GPIO's, etc.) which does stay asserted correctly. As a bonus, the single transfer synchronous messages complete faster than multi-part messages.

both optional After looking at AMD's CFI specification [1], both of the extended query tables are optional. Thus, it looks like relying that at least one of those tables exist is a bug in cfi_cmdset_0002. This patch inverts the logic and checks for unlock function pointers before exiting on error. This approach leaves place to add a call to a fixup function to try to handle chips compatible with the early AMD specification from 1995 [2].
