This board seems to be popular in commercial environments for evaluating ARM in deeply embedded applications. I would like to add support for this board in the mainline U-Boot but "new" architecture support is needed first (ARMv7-M variant is slightly different from other ARMs). This patch implements basic architecture support which I am already using for my own Linux booting setup with this board. I would really appreciate your opinion on feasibility of this board in mainline U-Boot tree and correctness (or not) of this patch. I tried to re-use as much as possible from existing ARM code.

In general this looks OK.  Can you also post the STM32F429 board port
code?  Thanks!
