Including both trace and verified boot series, the size drops a little for
ARM and powerpc:

(the wip commit is just a patman change). You can see the text size drops
by 100-200 bytes. This is all due to the bootm refactor which removed
duplicated code.
If you are interested you can see this in the detail view. Commit 16
removes quite a bit of code. Commit 25 adds up to 80 bytes of text.
