[coreboot] Lenovo Thinkpad Yoga 11e (1st Gen, Win10 variant)

[John Lewis]

Again, I'm being Captain Vague here, but I'm fairly sure Ron/similar
have advised on the difficulty of doing something like this before - not
that it's as hard as doing a port from scratch, but that you still do
need pretty in-depth firmware/c experience to do it.

Regards,

John.
