So we'd need a lot better high level description than this:

 - a bit of background description: what are the advantages of having
   the kernel image in non-RAM (flash), etc.

 - on what hardware/bootloaders is or will be XIP supported?

Also, there should probably be some fail-safe mechanism included: such 
as to check whether caching attributes (MTRRs, PAT) are properly set 
for the XIP area (at minimum to not be uncacheable).

Thanks,
