Christian Lamparter 4fc48a8cf2 apm821xx: replace recovery image for the MBL with initramfs
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.

Christian Lamparter dc7efaefb5 apm821xx: add support for the Western Digital MyBook Live Series
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.
