brcm2708: add squashfs rootfs image
This patch adds a image with squashfs as the root filesystem.
A rootfs_data partition will be generated on the first boot
and placed inside the rootfs partition (just after the squashfs
image).
advantages:
- it is possible to migrate from an existing -ext4
installation and back via sysupgrade.
- existing partition layout will not be lost.
- slightly smaller image size.
- support for attendedsysupgrade
disadvantages:
- needs f2fs + tools as well. This is because fs-tools decides on the
blocksize of the sdcard. So either f2fs or ext4 can get choosen as
the rootfs_data filesystem (depends on the size of the root partition).
- rootfs_data is placed into the rootfs partition. This makes
it difficult for tools that expect a /dev/mmc0pX device.
It also makes it difficult for data recovery tools since they
might not expect to find a embedded partition or will be
confused.
For people with existing build configurations: make sure to include mkf2fs
and f2fsck package into the image... Otherwise the new -squashfs image will
boot of a ram-overlay and won't keep the configurations after a reboot.
