[U-Boot] [PATCH 0/5] nand: sunxi: Add SPL support for booting from NAND.

[Daniel Kochmański]

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
