This set applies on top of [1] and refactors the STM32 platform code in
order to attach to the M4 remote processor when it has been started by the
boot loader.

New to V5:
1) Added Bjorn's reviewed-by to patch 06.
2) Removed Loic's reviewed-by from patch 08, it has changed too much.

Patches that need to be reviewed: 7, 8, 9 and 10.

Tested on ST's mp157c development board.

Thanks,
Mathieu
