This patch adds the boot-part feature to the apm82181 sata target.
This makes it possible to configure the boot partition size with
the generic CONFIG_TARGET_KERNEL_PARTSIZE symbol.
Please note: For people using custom images: Just like with
CONFIG_TARGET_ROOTFS_PARTSIZE changing the value can cause
sysupgrade to repartition the device!

The rootfs-part feature flag ensures that
CONFIG_ROOTFS_PART_SIZE symbol will be present
at all times.

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.

The patch "images: bump default rootfs size to 256 MB"
a1f83bad60 caused a crash
during boot for the recovery images. This is because
both variants of the MyBook Live only have 256MB of RAM
and for the recovery option, the ext4 rootfs was simply
stored in the RAMDISK.
This patch replaces recovery image for the MBL with an
initramfs kernel.
In order to boot the initramfs (for recovery or development):
0. copy the initramfs and device tree into tftp's server directory
# cp *-initramfs-kernel.bin to /tftp-server/mbl.bin
# cp *-ext4-kernel.dtb to /tftp-server/fdt.bin
1. Connect the MyBook Live (Duo) serial port.
(Warning! Use a 3.3v level shifter).
2. Hit Enter during u-boot and insert these three lines:
# setenv serverip 192.168.1.254; setenv ipaddr 192.168.1.1;
# tftp ${kernel_addr_r} mbl.bin; tftp ${fdt_addr_r} fdt.bin
# run addtty addmisc; bootm ${kernel_addr_r} - ${fdt_addr_r}
Where 192.168.1.254 is your TFTP server.

This reverts commit 8c68c104ea.
It is used for apm821xx, which needs ext2 (not ext4) images for some
devices.

Hardware Highlights:
This patch adds support for Western Digital MyBook Live Series:
CPU: AMCC PowerPC UNKNOWN (PVR=12c41c83) at 800 MHz (PLB=200, OPB=100, EBC=100 MHz)
32 kB I-Cache 32 kB D-Cache, 256 kB L2-Cache, 32 kB OnChip Memory
Board: Apollo-3G - APM82181 Board, 1*SATA
DRAM: 256 MB (2x NT5TU64M16GG-AC)
FLASH: 512 kB (SST 39VF040)
Ethernet: 1xRGMII - 1 Gbit - Broadcom PHY BCM54610
WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
The MyBook Live Duo additionally features a 1x USB 2.0 host port
and can support a second hard-drive.
This target produces two images for a target.
1. ext4 image
The extracted/raw image can be directly installed on
the internal HDD via "dd if=img.ext4 of=/dev/sdX".
This can either be done in place with the stock MyBook Live
firmware via ssh. Or by removing the HDD and writing the image
with a different PC.
The the compressed images are useful for sysupgrade.
2. recovery.tar image for TFTP and Serial.
extract the recovery.tar to a TFTP server directory.
On the MyBook Live (Duo) serial port - Hit Enter during u-boot and insert:
# setenv serverip 192.168.1.254; setenv ipaddr 192.168.1.1; run net_self
Where 192.168.1.254 is your TFTP server.
