This patch converts the MyBook Live's recovery image to utilize the
multi-image method which integrates the device-tree binary directly
into the image.
The new initramfs can be loaded through the MyBook Live's U-boot
in the following way:
=> setenv ipaddr 192.168.1.1
=> setenv serverip 192.168.1.2
=> sata init; run addtty; tftp $kernel_addr_r wd_mybooklive-initramfs.bin; bootm
Waiting for PHY auto negotiation to complete... done
ENET Speed is 1000 Mbps - FULL duplex connection (EMAC0)
Using ppc_4xx_eth0 device
TFTP from server 192.168.1.2; our IP address is 192.168.1.1
Filename 'wd_mybooklive-initramfs.bin'.

# Netgear used an old uboot that doesn't have FIT support.
|
|
# So we are stuck with either a full ext2/4 fs in a initrd.
|
|
# ... or we try to make the "multi" image approach to work
|
|
# for us.
|
|
#
|
|
# Sadly, the "multi" image has to consists of three
|
|
# "fixed" parts in the following "fixed" order:
|
|
# 1. The kernel which is in $@
|
|
# 2. The (fake) initrd which is in $@.fakerd
|
|
# 3. The device tree binary which is in $@.dtb
|
|
#
|
|
# Now, given that we use the function for the kernel which
|
|
# already has a initramfs image inside, we still have to
|
|
# add a "fake" initrd (which a mkimage header) in the second
|
|
# part of the legacy multi image. Since we need to put the
|
|
# device tree stuff into part 3.
