[U-Boot] [PATCH 0/3] add support for the asus C201 chromebook (4GiB)

Build and boot tested on my chromebook, which was generously altered by
Simon Glass to have a servo header and also generously provided a servo
board itself to do debugging with.

It ''works'', but has a few oddities. I can't seem to get it to see my
external sdcard or a usb flash drive, so I've been having to ymodem my
kernel, fdt, and initramfs over to test booting (which does work). The
screen is a bit inconsistent on whether or not it activates any given
power cycle, but when it does work, it works right.

The changes to sdram_common.c were taken from coreboot, as it has
otherwise identical code (minus the if (!size_mb) block), and actually
works on my hardware.
