This adds various bits and pieces to enable generating a working example
of a full chain of trust up to dm-verity-protected rootfs level on Beagle
Bone Black.
The new initramfs is quite generic and should work for other SoCs as well
when using fitImage.
The following config can be used with current master poky,
meta-openembedded & meta-security to generate a BBB image using verified
boot and dm-verity.
