Christian Lamparter aed4799d6d apm821xx: build squashfs-rootfs images for the MBL
This patch adds support for squashfs as the root filesystem.

advantages:
 - migrate from a existing -ext4 installation and back
   with the sysupgrade utility
 - existing partition layout will not be lost during switch
 - slightly smaller image size as compared to the -ext4 image.

disadvantages:
 - needs f2fs + tools. This is because fstools rootdisk.c decides based
   on the partition size (currently root partitions > 100 MiB) f2fs is
   used as the rootfs_data filesystem.
 - rootfs_data is placed into the rootfs partition after the squashfs.
   This makes it difficult for tools that expect a /dev/sda${X} device.
   It also makes it difficult for data recovery tools as they might not
   expect to find a embedded partition or will be slightly confused.
   ... or will not support f2fs.

For people with existing build configurations: make sure to include mkf2fs
and f2fsck packages into the image. Otherwise the new -squashfs image will
only boot from the ram-overlay.

Note:
All overlay data (configurations/all installed packages/...) will be
placed in inside the rootfs partition (i.e. /dev/sda2) just after the
squashfs image.

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
