The asm-arm/unaligned.h includes linux/unaligned/access_ok.h This file is unsafe to be used on ARM, since it does an unaligned memory accesses which fails on ARM. Lookin at Linux the basic difference seems to be the header "include/asm-arm/unaligned.h". The Linux version of "unaligned.h" does *not* include "access_ok.h" at all. It includes "le_byteshift.h" and "be_byteshift.h" instead.

This patch corrects that by using PLATFORM_xxx instead of the name itself.

UBIFS requires fls(), which is not defined for arm (and some other architectures) and this patch adds it. The implementation is taken from Linux and is generic. ffs() is also defined for those that miss it. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
__set_bit and __clear_bit are defined in ubifs.h as well as in asm/include/bitops.h for some architectures. This patch moves the generic implementation to include/linux/bitops.h and uses that unless it's defined by the architecture. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net>
This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to support 4-bit ECC on TI DaVinci devices with large page (up to 2K) NAND chips. This ECC mode is similar to NAND_ECC_HW, with the exception of read_page API that first reads the OOB area, reads the data in chunks, feeds the ECC from OOB area to the ECC hw engine and perform any correction on the data as per the ECC status reported by the engine.

This patch adds a new "page" parameter to all NAND read_page/read_page_raw APIs. The read_page API for the new mode ECC_HW_OOB_FIRST requires the page information to send the READOOB command and read the OOB area before the data area.
