u-boot-arm/master rebased on current u-boot/master

Hello,

I have rebased u-boot-arm/master onto u-boot/master, as of this writing that's commit 4668a086bb0a769b741e3a4ffab85f1c41c7cdb8 (sandbox: Add asm/errno.h).

This is NOT a pull request: there are still at least one pull request to come from u-boot-marvell and individual patches.

The pull request should go out on thursday.

Any patches you think I should apply for this release, make sure they are assigned to me in patchwork; I'll go through mo todo list oldest patches first.

Amicalement,

Albert.
