[U-Boot] [PATH] at91: add hwecc method for nand

Hi, all. This is a patch to use the hardware ECC controller of the AT91SAM9260 for the AT91 nand. Taken from the kernel 2.6.33. To use this it is necessary to add two definitions in config: CONFIG_ATMEL_NAND_HWECC CONFIG_SYS_NAND_ECC_BASE (AT91_ECC for the AT91SAM9260 and AT91_ECC0 for the AT91SA
