[U-Boot] [PATCH v2 3/5] at91: atmel_nand: Update driver to support Programmable Multibit ECC controller

2012-08-15 Thread Josh Wu
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.
