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.

Russell Senior reported an issue with the MR24 initramfs kernels:
> ## Booting kernel from Legacy Image at 00c10000 ...
> Image Name: POWERPC LEDE Linux-4.4.19
> Created: 2016-08-31 11:57:05 UTC
> Image Type: PowerPC Linux Kernel Image (gzip compressed)
> Data Size: 2155723 Bytes = 2.1 MiB
> Load Address: 00000000
> Entry Point: 00000000
> Verifying Checksum ... OK
>Wrong Ramdisk Image Format
>Ramdisk image is corrupt or invalid
For the MR24, the kernel is uploaded to 0x10000. The ramdisk starts
at 0x200000. This leaves the kernel with just 0x1f0000 bytes = 1984kb.
This patch adds a size check so the image creation script will abort
instead of producing a unbootable initramfs image. A separate patch
"apm821xx: Fix initramfs image for the Meraki MR24" which fixed the
reported issue was submitted earlier.

When gzip is used, our kernel is too large and this causes the ramdisk
to be at the wrong offset. Fix by moving to lzma.

Now that the "sysupgrade-nand" step is used by non-NAND targets as well,
rename it to "sysupgrade-tar" to make it more generic.

The MR24's u-boot takes it sweet time decompressing the
LZMA-packed initramfs image. A user reported that
compared to the old gzip method in v2: it "takes a ton
longer to decompress like 4\x the old boot time for
decompression".
This patch also fixes a issue with the WNDR4700's initramfs
image getting to big and causing the following u-boot crash
during the decompression:
"Uncompressing Multi-File Image ... Error: inflate() returned -5
out-of-mem or overwrite error - must RESET board to recover"
This patch fixes both issues by reverting the MR24's initramfs
compression method back to gzip. And choosing to compress the
initramfs within the initramfs image as LZMA by default.

WARNING: The serial port needs a TTL/RS-232 v3.3 level converter!
INFO: Since this device only has a NAND chip. I opted for going with
root.squashfs in a UBI volume. There's no squashfs/jffs2 image.
This target produces three images.
a. netgear factory image
This image can be used to flash the Netgear WNDR4700 via the
firmware recovery mechanism and the web admin site.
The bootloader can be instructed to do a firmware recovery via the
# fw_recovery
command. It will start a tftp server and listen on 192.168.1.1
(the ipaddr variable in u-boot) for incoming, binary tftp clients.
The firmware recovery mechanism is also started if any of the flash
content which contains the kernel, device-tree definitions or the
(fake)rootfs fails to verify or load.
b. sysupgrade.tar image for sysupgrade
An sysupgrade will replace the entire current LEDE installation
with a newer version. This does include the kernel and the ubi rootfs
partition. The configuration can be carried over automatically as well
if desired.
simply copy the sysupgrade.tar to a the WNDR4700 running LEDE and run:
root@lede:~# sysupgrade sysupgrade.tar
and let it reboot.
Note: The devicetree flash area is NOT updated. Until the devicetree
definition is stable, this can lead to all sorts of hardware
detection problems! So make sure, if you experience issues: try
the fw_recovery. If you are unsure whenever this affects you:
test if you can reproduce your issue with the initramfs method.
As it will always have up-to-date device-tree definitions.
c. initramfs image for TFTP (for development and testing)
To use the initramfs method, follow the following steps:
1) Move the "lede-apm821xx-netgear-WNDR4700-initramfs-kernel.bin"
file to to the root directory of your TFTP server.
2) rename it to wndr4700.bin
3) On the WNDR4700 - Hit Enter during u-boot and insert:
# tftp 400000 wndr4700.bin; run addtty; bootm 400000 -
This will boot the LEDE image.
Note: The default tftp server is 192.168.1.7, if you want to change it:
# setenv serverip 192.168.8.7;
Note2: The default address for the WNDR4700 is 192.168.1.1:
# setenv ipaddr 192.168.8.8;
Note: Connect you tftp server on the last LAN port (not the WAN)
Note: The firmware for the USB 3.0 Host chip is not included anymore.
Therefore the two USB 3.0 ports will not work without the
uPD7070x-firmware package installed.

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.
