apm821xx: switch MR24's initramfs to multi-image method
The recent change to switch to gcc 7.3 broke the image
generation code, as the kernel would no longer fit into
KERNEL_SIZE.
This patch fixes the issue by reworking the initramfs
creation and packaging, which will get rid of the
KERNEL_SIZE check in the process.
This new initramfs can be loaded through the MR24 U-boot
in the following way:
=> setenv ipaddr 192.168.1.1
=> setenv bootargs console=ttyS0,$baudrate
=> tftpboot c00000 192.168.1.2:meraki_mr24-initramfs-kernel.bin
[...]
Load address: 0xc00000
Loading: ################################################ [...]
done
Bytes transferred = 5952544 (5ad420 hex)
=> bootm $fileaddr
\## Booting kernel from Legacy Image at 00c00000 ...
