2013-08-05mtd: jedec_probe: fix LH28F640BF definitionAndrea Adami1-6/+7
Zaurus 5500 contains 2 LH28F640BFHE-PTTL90 (64M 4Mx16) and the LH28F640BFHE-PTTL90.pdf datasheet available on the net shows the exact erasesize and the OTP support. At the moment only jedec_probe can discover the chip and the NOR is mounted read only probably because of wrong vpp. Signed-off-by: Andrea Adami <andrea.adami@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2011-03-11mtd: jedec_probe: initialise make sector erase command variableAntony Pavlov1-2/+3
In the commit 08968041bef437ec363623cd3218c2b083537ada (mtd: cfi_cmdset_0002: make sector erase command variable) introdused a field sector_erase_cmd. In the same commit initialisation of cfi->sector_erase_cmd made in cfi_chip_setup() (file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem: ... cfi->cfi_mode = CFI_MODE_CFI; cfi->sector_erase_cmd = CMD(0x30); ... But for the JEDEC chips this initialisation is not carried out, so the JEDEC chips have sector_erase_cmd == 0. This patch adds the missing initialisation.

2011-03-11mtd: jedec_probe: Change variable name from cfi_p to cfiAntony Pavlov1-16/+16
In the following commit, we'll need to use the CMD() macro in order to fix the initialisation of the sector_erase_cmd field. That requires the local variable to be called 'cfi', so change it first in a simple patch.

2008-11-05[MTD] [NOR] Fix cfi_send_gen_cmd handling of x16 devices in x8 mode (v4)Eric W. Biederman1-6/+4
For "unlock" cycles to 16bit devices in 8bit compatibility mode we need to use the byte addresses 0xaaa and 0x555. These effectively match the word address 0x555 and 0x2aa, except the latter has its low bit set. Most chips don't care about the value of the 'A-1' pin in x8 mode, but some -- like the ST M29W320D -- do. So we need to be careful to set it where appropriate. cfi_send_gen_cmd is only ever passed addresses where the low byte is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are affected by this patch, by masking in the extra low bit when the device is known to be in compatibility mode. [dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa] v4: Fix stupid typo in cfi_build_cmd_addr that failed to compile I'm writing this patch way to late at night. v3: Bring all of the work back into cfi_build_cmd_addr including calling of map_bankwidth(map) and cfi_interleave(cfi) So every caller doesn't need to. v2: Only modified the address if we our device_type is larger than our bus width.

The change to the generic probe to look for the smallest width of chip first is causing some problems on boards with a single 16bit device. The problem seems to be the jedec_match() is truncating the device-id read from the table to match against the one read from the hardware, causing a match against the partial id of some chips with 16bit IDs (such as the SST39LF160) This fixes things for my own board, but something may need to be done if the same problem is exhibited for chips with an 8bit ID Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
