[PATCH u-boot 0/1] RFC: How to configure boot options?

As part of the change-over from an initramfs-based boot sequence to a
direct rootfs boot, we need to change some of the boot options for
u-boot.  I expect these to change a few times in the near future as we
also transition to UBI-managed volumes and we figure out how to set
u-boot environment options to switch between different UBI kernels and

This is really independent from the current ast-*-defconfigs, in that
those currently select between different network options.  I suspect
we do not N*M combinations of defconfigs for network*image-structure.
I plan to make a MACHINE_FEATURE (or DISTRO_FEATURE) in bitbake to
control this, but looking for feedback on how we should change u-boot.

Ideally, to me, this would have been passed in via the config file and
we could have used config-snippets in Yocto like we do for the kernel.
Due to the way u-boot builds, I could not find a simple way to even
change this option from a include/config/ast-common.h #define into a
machine_config driven option.

Anyone have ideas?
