The SPARE_AREA_SKIP_BYTES register is reset when the controller reset signal is toggled. Yet, this register must be configured to match the content of the NAND OOB area. The current default value is always set to 8 and is programmed into the hardware in case the hardware was not programmed before (e.g. in a bootloader) with a different value. This however does not work when the block is reset properly by Linux. On Altera SoCFPGA CycloneV, ArriaV and Arria10, which are the SoCFPGA platforms which support booting from NAND, the SPARE_AREA_SKIP_BYTES value must be set to 2. On Socionext Uniphier, the value is 8. This patch adds support for preconfiguring the default value and handles the special SoCFPGA case by setting the default to 2 on all SoCFPGA platforms, while retaining the original behavior and default value of 8 on all the other platforms.
