[coreboot] coreboot on ASRock H81M-HDS cannot load a payload

[ron minnich]

you can actually make kernels surprisingly small. I've just built a 2M
kernel + u-root initramfs for example.

This kernel has very little in it.

If emmc support blots the kernel too large, I may write a Go
programmed IO driver for emmc to run in user mode, and
see if that is smaller.
