- Subject: 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.
