mtd: nand: mxs invalidate dcache before DMA read Follow linux dma flow: Before DMA read, be sure to invalidate the cache over the address range of DMA buffer to prevent cache coherency problems. After DMA read, invalidate dcache again. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Acked-by: Marek Vasut <marex@denx.de> Acked-by: Tim Harvey <tharvey@gateworks.com>
mtd: nand: mxs support oobsize bigger than 512 If ecc chunk data size is 512 and oobsize is bigger than 512, there is a chance that block_mark_bit_offset conflicts with bch ecc area. The following graph is modified from kernel gpmi-nand.c driver with each data block 512 bytes. We can see that Block Mark conflicts with ecc area from bch view. We can enlarge the ecc chunk size to avoid this problem to those oobsize which is larger than 512. | P | |<----------------------------------------------------------------->| | | | (Block Mark) | | P' | | | | |<--------------------------------------------------->| D | | O'| | |<--------->| |<->| V V V V V +---+--------------+-+--------------+-+--------------+-+----------+-+---+ | M | data |E| data |E| data |E| data |E| | +---+--------------+-+--------------+-+--------------+-+----------+-+---+ ^ ^ | O | |<---------------->| P : the page size for BCH module. E : The ECC strength. G : the length of Galois Field. N : The chunk count of per page. M : the metasize of per page. C : the ecc chunk size, aka the "data" above. P': the nand chip's page size.

mxs_nand: Fix ECC strength for NAND flash with OOB size of 224 On a board with an i.mx28 and a Micron MT29F4G08ABAEAH4, Linux says: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron MT29F4G08ABAEAH4), 512MiB, page size: 4096, OOB size: 224) the ECC strength is 16. root@(none):/sys/devices/virtual/mtd/mtd0# for i in ecc_strength oobsize subpagesize; do echo $i = `cat $i`; done ecc_strength = 16 oobsize = 224 subpagesize = 4096 The ECC strength was not properly discovered by U-Boot causing the data written by Linux to return an -74 (EBADMSG) when read from U-Boot. This patch fixes mxs_nand_get_ecc_strength() to function in case of a NAND flash with page_data_size = 4096 and page_oob_size= 224.

mtd: resync with Linux-3.7.1 This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.
