----------------------------------------------------------------------------
8a06abf132f8: bcm2708: Convert framebuffer driver over to new format
* Remove from raspberry_pi bootloader (which should die soon)
* Change to use new arm device layout
* Create arch_mailbox to check arm mailboxes (WIP)
c798e80b79b6: raspberry_pi: Move over to u-boot.
* The raspberry_pi loader wasn't in great shape anyway,
but could still contain some valueable code.
