uboot patches up the amount of RAM it finds into the FDT. It might
patch up clock speed too, I don't remember. I haven't seen it add
serial numbers but it might, not sure which serial numbers.

There has been talk for several years about turning uboot into a bunch
of device drivers and using FDT to control it. Allwinner has done that
with the fex implementation. The uboot work is still in the talking
about it phase.
