Very cool! Thanks so much for providing this! I'll add it to my tree.

I'll add these as well, thanks so much!

So this is likely due to the ARCH_VEXPRESS option having dependencies 
that aren't met.

They way I usually sort this out is, after building the config.  I call 
make menuconfig and hit "/ARCH_VEXPRESS" and it will show the current 
state of the dependencies for that option. The ones that aren't set, I 
then add to the config fragment.

But as the larger point about documentation, its severely lacking right 
now.  My apologies for that.  I'll see if I can find some time in the 
near future to improve this. If you have any specific documentation 
suggestions, I'd be happy to incorporate them .
