[U-Boot] u-boot on beagleboard finds incorrect memory size.

[wilsonjonathan]

The u-boot loader is showing an incorrect size in the memory, and
passing the invalid information to the kernel.

As you can see DRAM is showing as 1 Gib when the beagleboard doesn't
have this much memory.

and the kernel boot shows it also has the wrong memory constraints.

This is from the linaro-stable and if I worked out git correctly the
last commit is and i'm in master?

(sorry I don't know git very well bar git clone)
