rootfs.cpio is the cpio version of rootfs.ext2, both should represent
the same filesystem in different serialized formats.
I've added it to this updated zip:
https://github.com/cirosantilli/linux-kernel-module-cheat/releases/download/test-replay-arm/images2.zip
The previous .zip didn't have the .cpio, then I later made Buildroot
generate it as well to try out the -initrd method.
I'm using this branch for my testing:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/rr with
"./build -a arm && ./recarm"
