Applied on todays master and tested with a Thumb build of a mxs U-Boot.

Can’t say by just looking at it. And since I did this patches while working
on a ARM926EJS I can’t test it on that board as Linux requires ARMv7(M)
to build a Thumb2 only kernel. Will try it once I’m in front of a suitable
board again. Thanks for the hint.
