----------------------------! The following lines in drivers/mtd/chips/cfi_cmdset_0001.c are suspicious: #if !FORCE_WORD_WRITE
{ CFI_MFR_ANY, CFI_ID_ANY, fixup_use_write_buffers, NULL },
#endif
{ CFI_MFR_ST, 0x00ba, /* M28W320CT */ fixup_st_m28w320ct, NULL },
{ CFI_MFR_ST, 0x00bb, /* M28W320CB */ fixup_st_m28w320cb, NULL }, There are several issues: 1. The documentation lists the chip ID as 0x88ba/0x88bb, not 0x00ba/0x00bb. A
vendor based a patch for the M28W640 part on these lines and it was indeed
broken because of the zeroed high bytes. 2. The fixup_st_m28w320ct function zeroes cfi->cfiq->BufWriteTimeoutTyp, but
fixup_use_write_buffers tests it first because it is earlier in the array. So
fixup_use_write_buffers should be moved to the end I think. 3. Knowing next to nothing about MTD, I am not clear on what "top" vs. "bottom"
parts are all about. The card I am using does not have both. Only one of the
M28W320 fixups is clearing cfi->cfiq->BufWriteTimeoutTyp -- should they both do
that? Joe Buehler [ The message is modified by s@parator ]
