at91: atmel_nand: Update driver to support Programmable Multibit ECC controller 2012-09-01T15:06:14+00:00 Wu, Josh Josh.wu@atmel.com 2012-08-23T00:05:36+00:00 bdfd59aa0f00ea86b1ecf44303790eea355b8585 The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros. It is tested in 9x5 serial boards. Signed-off-by: Josh Wu <josh.wu@atmel.com> [rebase] Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
