I'll take that part, the pxa_defconfig which covers all pxa boards in
arch/arm/mach-pxa. I have a prototype, which of course doesn't boot on any of my
pxa platforms (breaks in the very early bootstrap code I think, DEBUG_LL is the
next stage).

Actually I've not even looked if a single kernel covering pxa2xx and pxa3xx is
possible (since recently clock handling was a blocker).

Once I have something that at least shows me a sign of life, I'll submit an RFC
patch. This work will be orthogonal to Sergei's one, as it is aimed at having
one defconfig compiling all mach-pxa/*.c files and the drivers referenced by
them. This won't allow removing defconfig files until I have a good idea why my
boards are not booting (lubbock, mainstone, mioa701, zylonite, cm-x300).

Cheers.
