2006-05-29[MTD] NAND Replace oobinfo by ecclayoutThomas Gleixner1-8/+6
The nand_oobinfo structure is not fitting the newer error correction demands anymore. Replace it by struct nand_ecclayout and fixup the users all over the place. Keep the nand_oobinfo based ioctl for user space compability reasons. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-29[MTD] NAND Consolidate oobinfo handlingThomas Gleixner1-1/+1
The info structure for out of band data was copied into the mtd structure. Make it a pointer and remove the ability to set it from userspace. The position of ecc bytes is defined by the hardware and should not be changed by software. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove read/write _ecc variantsThomas Gleixner1-58/+17
MTD clients are agnostic of FLASH which needs ECC suppport. Remove the functions and fixup the callers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove readv/readv_eccThomas Gleixner1-2/+0
These functions were never implemented and added only bloat to partition and concat code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Remove nand writev supportThomas Gleixner1-140/+0
NAND writev(_ecc) support is not longer necessary. Remove it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Introduce MTD_BIT_WRITEABLEJoern Engel1-1/+1
o Add a flag MTD_BIT_WRITEABLE for devices that allow single bits to be cleared. o Replace MTD_PROGRAM_REGIONS with a cleared MTD_BIT_WRITEABLE flag for STMicro and Intel Sibley flashes with internal ECC. Those flashes disallow clearing of single bits, unlike regular NOR flashes, so the new flag models their behaviour better. o Remove MTD_ECC. After the STMicro/Sibley merge, this flag is only set and never checked. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2006-05-23[MTD] Introduce writesizeJoern Engel1-36/+36
At least two flashes exists that have the concept of a minimum write unit, similar to NAND pages, but no other NAND characteristics. Therefore, rename the minimum write unit to "writesize" for all flashes, including NAND. Signed-off-by: Joern Engel <joern@wh.fh-wedel.de>
2006-05-12OneNAND: fix block command typoKyungmin Park1-1/+1
We need to check block cmd only instead with comparing with cmd Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2006-05-12OneNAND: One-Time Programmable (OTP) supportKyungmin Park1-3/+310
One Block of the NAND Flash Array memory is reserved as a One-Time Programmable Block memory area. Also, 1st Block of NAND Flash Array can be used as OTP. The OTP block can be read, programmed and locked using the same operations as any other NAND Flash Array memory block. OTP block cannot be erased. OTP block is fully-guaranteed to be a valid block.

2006-05-12OneNAND: Handle erase correctly in Double Density Package (DDP)Kyungmin Park1-0/+6
There's erase bug in DDP. We need to add DDP select in erase Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2006-05-12OneNAND: Write oob area with aligned size, mtd->oobsizeKyungmin Park1-2/+5
There's some problem with write oob in serveral platform. So we write oob with oobsize aligned (16bytes) instead of 3 bytes (from {2, 3}) Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

2006-05-12OneNand: Fix free byte positions.Jarkko Lavinen1-1/+2
Some free byte positions at onenand_oob_64 were wrong. This was also reported by Christian Lehne. 3 byte slots are at 2+16*i and 2 byte slots at 14+16*i. Signed-off-by: Jarkko Lavinen <jarkko.lavinen@nokia.com>
