Two fixes for the nand_wait() function in
drivers/nand/nand_base.c:
1. Use correct timeouts. The original timeouts in Linux
source are 400ms and 20ms not 40s and 20s
2. Return correct error value in case of timeout. 0 is
interpreted as OK.

This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is
defined
and the write crosses a block boundary. The pointer to the verification
buffer (bufstart) is not being updated to reflect the starting of the
new
block so the verification of the second block fails.
CHANGELOG:
* Fix NAND FLASH page verification across block boundaries
* For READ_STATUS and READID commands always 8 bytes need to be read from
NDDB. Otherwise they stay there and get send to flash as the first data
word when writing.
* In nand_base.c the oob variable is not reset so this->oob_buf is
overwritten what eventually screws up the bad block descriptor table.
code and in SoC code). Boards using the old way have CFG_NAND_LEGACY and
BOARDLIBS = drivers/nand_legacy/libnand_legacy.a added. Build breakage for
NETTA.ERR and NETTA_ISDN - will go away when the new NAND support is
implemented for these boards.
