In the past, the MX60(W)'s recovery images always had problems
with the size restriction and never really worked without manual
intervention. This patch reworks the initramfs, which allows the
device to ease up on the impossible tight kernel size requirements
for the initramfs image.
This new initramfs can be loaded through the MX60(W) U-boot
in the following way:
=> setenv bootargs console=ttyS0,$baudrate
=> tftpboot $meraki_loadaddr meraki_mx60-initramfs-kernel.bin
[...]
Load address: 0x800000
Loading: ################################################ [...]
done
[...]
=> bootm $fileaddr
\## Booting kernel from Legacy Image at
00800000 ...
