This patch series will add PMECC support for atmel at91sam9x5ek in u-boot.
The NAND flash driver patch is ported from kernel patch. The main different
from kernel patch is
the modification about registers access part. in this version it via a register
structure to access.
It is tested in atmel AT919G25EK board.
Changes since v2:
adapt atmel nand driver to CONFIG_SYS_NAND_SELF_INIT. It use a new
board_nand_init(void) function.
Add README doc for Atmel PMECC.
Add timeout for PMECC read hw status.
refine code according to Andreas and Scott's comments.
Josh Wu (5):
at91: atmel_nand: extract HWECC initialization code into one
function: atmel_hw_nand_init_param().
at91: atmel_nand: remove unused variables.
at91: atmel_nand: Update driver to support Programmable Multibit ECC
controller
at91: 9x5: change SMC config timing that both works for PMECC &
non-PMECC.
at91: 9x5: Enable PMECC for 5series ek board.
