[U-Boot] [PATCHv3 4/4] igep00x0: UBIize

Mon Jan 11 00:18:10 CET 2016
This patch converts IGEP board to use UBI volumes for environment,
u-boot, kernel... With exception of first four sectors read by SoC
boot ROM whole NAND is UBI managed. Code is too big, so I dropped
CONFIG_SPL_EXT_SUPPORT to make it fit. It is meant more likely as a test
of Thomas' patch, so more people can play with that.
