[U-Boot] [PATCH v2 0/5] at91: 9x5: Enable PMECC(Programmable Multibit ECC controller) support

[Josh Wu]

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 v1:
   Add two patches that enable PMECC in 9x5 board.
   Nand flash driver: 
     Change 'ecc' array's type from u32 to u8 in structure pmecc_regs (u32 ecc[11] -> u8 ecc[44]). That will make PMECC write correctly.
     enable 4k-page nand flash pmecc support.
     fix coding style errors and warnings.

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.
