Also update the device-tree filename since this currently differs from

The all current Rockchip SoCs supporting 4GB of ram have problems
accessing the memory region 0xfe000000~0xff000000. Actually, some IP

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

The ChromeOS kernel reads the RAM settings from PMU_SYS_REG2 and expects
the bootloader to store the necessary information there. We're using
the same register to pass the same information between the SPL and
U-Boot but in a slightly different format.
Change this to use the format expected by the Linux DMC driver so that
the system doesn't hang in Linux by misconfiguring the RAM.
This is almost the same as commit b5788dc ("rockchip: rk3288: correct
sdram setting") which was reverted in commit b525556 ("Revert "rockchip:
rk3288: correct sdram setting"") but parenthese have been added to apply
the mask correctly when reading the "bw" setting and a couple of minor
style issues have been fixed to keep check_patch.pl happy.
