Does this work if there is no ti-core-initramsfs.cpio.xz in the boot
partition? Or is this assuming that there will always be an initramfs?
Because that is a problem if it is required all the time in all cases
for all platforms.
Additionally, this is being done in meta-arago, but the
ti-core-initramfs is staged in meta-ti so that it is available for all
distros.
Is this something that should move to meta-ti? Are these settings
really a distro thing? Or a BSP thing?
