The all current Rockchip SoCs supporting 4GB of ram have problems accessing the memory region 0xfe000000~0xff000000. Actually, some IP controller can't address to, so let's limit the available range. 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.
