This is a series of patches to enable nand read functionality on sunxi
devices. It uses DMA and is able to read from syndrome partitions and
normal ones. Additionaly mksunxiboot tool is patched to be able to
format resulting binary to be able to read from BROM, so NAND SPL builds
are now possible. a20_nandread command is added for conveniance.
Afaik DMA controller doesn't vary between a10 and a20, so this should
work on a10 devices, but due to no a10 hardware it wasn't tested.
Daniel Kochmański (4):
sunxi: nand: add minimal nand driver (reading flash only).
sunxi: mksunxiboot: increase block size, so checksum is correct on
nand
sunxi: nand: add nand spl boot option
sunxi: nand: add a20_nandread command
