This patchset adds minimal SPL driver for reading from A20 nand partitions utilizing DMA controller. It supports randomization and syndrome partitions.
Since BROM reads second syndrome partition, if first SPL checksum doesn't match, additional U-Boot offset may be provided to load backup U-boot from second block of second page.
To simplify loading many files (devicetree, kernel, sourcable boot script) additional parameter is added, which allows preloading multiboot image into memory directly from SPL.
Additionally conveniance function a20_nandread has been added, which utilizes SPL driver on normal U-Boot.
Best regards, Daniel Kochmański
