The all current Rockchip SoCs supporting 4GB of ram have problems

This patch fixes a bug which found in miniarm-rk3288-4GB board. The
U-Boot was relocated to 0xfef72000, and .bss variants was also
relocated, such as do_fat_read_at_block. Once eMMC controller transfer
data to do_fat_read_at_block via DMA, DMAC can't access more than
0xfe000000. So that DMAC didn't work sane.

This patch could fix a bug while booting to kernel, which could be reproduce on 4 GB board. I hope someone who has 4 GB board could test it .
