Just as simple as keeping a few generic options
(add -g, debug spinlocks, enable premept) but changing boards from
rpxcllf to rpxlite.
And at the same time have a good textual description availbale for
the board which I am going to select.
"This is a variant of the XXX board, with additional 2 Megs
of Falsh, and the Ethernet port moved from FCC1 to FCC2."
This is becoming off-topic so lets stop that until something is
ready for u-boot. Then we can take it in the right context.

I will not say current .config in the kernel are 'readable' as such,
it's just a bunch of defines seperated by a few headlines.
