This adds Large page support for 8xx and uses it
for all kernel RAM.
Further usage is possible, IMAP_ADDR and on board
flash comes to mind.
There is one bit free the pte which could be used for
selecting different large page sizes but that is for another
day.
- Dan, what do you think :)
Joakim Tjernlund (3):
8xx: replace _PAGE_EXEC with _PAGE_PSE
8xx: Support LARGE pages in TLB code.
8xx: Use LARGE pages for kernel RAM.
