This series adds a nand ecclayout command to davinci nand that allows the ecclayout of the current nand device to be changed during run time. This feature is useful when using u-boot to write something to nand flash that will be read by other applications, such as ROM bootloader, that expects a different ECC layout. In that case, change the current nand device ecclayout using the "nand ecclayout set" command before writing the data to nand flash.
Based on u-boot.git/master
