2006-05-23[MTD] Remove read/write _ecc variantsThomas Gleixner
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 Gleixner
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 Gleixner
NAND writev(_ecc) support is not longer necessary. Remove it. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-22[MTD] Introduce MTD_BIT_WRITEABLEJoern Engel
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>
2006-05-22[MTD] Introduce writesizeJoern Engel
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 Park
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 Park
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. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2006-05-12OneNAND: Handle erase correctly in Double Density Package (DDP)Kyungmin Park
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 Park
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 Lavinen
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>

2006-01-08[PATCH] fix more missing includesTim Schmielau
Include fixes for 2.6.14-git11. Should allow to remove sched.h from module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390. Probably more to come since I haven't yet checked the other archs.
