[OE-core] [PATCH 3/3] core-image-minimal-initramfs: use initramfs-framework by default

[Cal Sullivan]

Hi Wei Tee,

I'm not sure what is causing the issue you're seeing when trying to run 
the selftests, but I was able to track down the issue causing the 
selftests to fail in normal usage.

Apparently, only systemd-boot sets no "root=" kernel command line 
parameter when booting live. Our other bootloaders (grub, syslinux) set 
root=/dev/ram0. The selftests use syslinux.

 From what I can tell from the kernel docs, this is basically just a 
sentinel value to say "mount the initrd as root":
https://www.kernel.org/doc/html/v4.11/admin-guide/initrd.html

We already have the procedure correct, and just have to account for 
/dev/ram0 as well now.

I'll send a patch for it.

Thanks,
Cal
