e79b096ee1 brcm2708: convert to metadata
This patch converts all the raspberrypi images to utilize
the common metadata-based image verification.

Note: the CM1 and CM3 currently use the same "rpi-cm"
boardname.

a48e5bea12 brcm2708: restore /boot/config.txt before reboot
The Raspberry Pi bootloader reads configuration values from config.txt
in the boot partition. This file allows to specify the amount of memory
to assign to the GPU, the license keys for hardware MPEG-2 and VC-1
decoding, Device Tree parameters and overlays, and lots of other things.

Since sysupgrade only restores the configuration after booting the newly
flashed image, these values will not be active, even if sysupgrade would
save /boot/config.txt. To solve this, add the file to the files to be
backed up, and restore it in platform_copy_config, before reboot.

3339f41d26 brcm2708: implement sysupgrade image check
Implement a crude but functioning sysupgrade image check for the
Raspberry Pi. The code only checks if the master boot record boot
signature (0x55aa) is present in the first 512-bytes at the correct
location. This can prevent the odd bricking of a system when flashing
the wrong file.

7ce3e1fd3c brcm2708: keep boot partition mounted to allow users to change config.txt
This way it's easier to configure device tree overlays, customize other
parameters...

2de7910102 brcm2708: Implement sysupgrade
Implement sysupgrade for Raspberry Pi, similar to the way it is done on x86:
The config files are saved in the boot partition and moved to where they are
normally expected in preinit.

Also add optional gzip compression for the SD card image, since this can save
a lot of space (76M vs 6M), also similar to x86.
