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.
