This patch is required, in conjunction with the patch submitted to linux-mtd [1], to access the flash memory device in the GLAN Tank. Without the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 ... physmap-flash physmap-flash.0: map_probe failed whereas with the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 Found: ST M29W400DB physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank number of JEDEC chips: 1 cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness. ... cmdlinepart partition parsing not available Searching for RedBoot partition table in physmap-flash.0 at offset 0x70000 No RedBoot partition table detected in physmap-flash.0 The change made by this patch is required because the ST M29W400DB flash memory chip in the GLAN Tank is used in 16 bit bus mode (~BYTE pin is high when the board is powered on).
