mtd: remove duplicate assignment of chip->state

2011-05-25T01:11:13Z

This is a trivial patch which removes unnecessary assignment of chip->state in put_chip(). It's duplicated. Signed-off-by: Tadashi Abe Acked-by: Joakim Tjernlund Signed-off-by: David Woodhouse

mtd: fix hang-up in cfi erase and read contention

2011-05-25T01:11:11Z

cfi erase command hangs up when erase and read contention occurs. If read runs at the same address as erase operation, read issues Erase-Suspend via get_chip() and the erase goes into sleep in wait queue. But in this case, read operation exits by time-out without waking it up. I think the other variants (0001, 0020 and lpddr) have the same problem too. Tested and verified the patch only on CFI-0002 flash, though. Signed-off-by: Tadashi Abe Acked-by: Joakim Tjernlund Signed-off-by: David Woodhouse

mtd: cmdset_0002: add CFI 1.5 support for S29GL-S

mtd: cfi: fix writebufsize initialization

2011-03-11T14:22:46Z

When initializing mtd->writebufsize, we must take into account possible flash chip interleaving. Wrong writebufsize initialization caused UBIFS recovery issues resulting in unmountable UBIFS file system on NOR flash partitions.

mtd: fix race in cfi_cmdset_0001 driver

2011-03-11T12:09:07Z

As inval_cache_and_wait_for_operation() drop and reclaim the lock to invalidate the cache, some other thread may suspend the operation before reaching the for(;;) loop. Therefore the loop must start with checking the chip->state before reading status from the chip.

mtd: jedec_probe: initialise make sector erase command variable

2011-03-11T12:05:54Z

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.

mtd: jedec_probe: Change variable name from cfi_p to cfi

2011-03-11T12:05:24Z

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.
