[U-Boot] [PATCH 24/28] armv8/ls2085aqds: NAND boot support

York Sun
2015-03-19T16:45:55Z

From: Scott Wood <scottwood@freescale.com>

This adds NAND boot support for LS2085AQDS, using SPL framework.

To form a NAND image, append u-boot-with-spl.bin after a proper
nand boot RCW and flash to the beginning of NAND.
