ST-Ericsson ux500 BSP contents

[Arnd Bergmann]

I finally got to this and wrote up a summary of the contents of the ST-E BSP
that we are mirroring on the Linaro git server:

I did not write up my recommendations of how to proceed, but it should give
an idea of the work in front of us/them.

Linus, if you see any significant omissions or mistakes, please correct me.
