This remedies an issue with the MBL Duo if both disks are inserted
and contain OpenWrt. kernel and dtb would be loaded from SATA 1:1
while rootfs (/dev/sda2) would be mounted on SATA 0:1.
Such a mix&match would obviously only work if both OpenWrt versions/
builds are identical, and especially fail after sysupgrade upgraded
the system disk on SATA 0:1.
The fallback to SATA 1:1 needs to be kept for MBL Single (only has
SATA 1:1) and MBL Duo with one disk inserted on SATA 1:1. To speed
up booting in those cases, the unneccesarily doubled "sata init"
will only be called once. (In theory it could be omitted completely
since the on-flash boot script already initializes SATA to load the
on-disk boot script.)
Tested on MBL Duo (all possible combination of disks) and MBL Single

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.
