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.

# 1. The kernel which is in $@

# 2. The (fake) initrd which is in $@.fakerd

# 3. The device tree binary which is in $@.dtb

# 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.
