8xx: invalidate non present TLBs
8xx: Update TLB asm so it behaves as linux mm expects.
8xx: Tag DAR with 0x00f0 to catch buggy instru
8xx sometimes need to load a invalid/non-present TLBs in
it DTLB asm handler.
These must be invalidated separaly as linux mm don't.

Update the TLB asm to make proper use of _PAGE_DIRY and _PAGE_ACCESSED.
Get rid of _PAGE_HWWRITE too.
Pros:
- I/D TLB Miss never needs to write to the linux pte.
- _PAGE_ACCESSED is only set on TLB Error fixing accounting
- _PAGE_DIRTY is mapped to 0x100, the changed bit, and is set directly
dcbz, dcbf, dcbi, dcbst and icbi do not set DAR when they
cause a DTLB Error. Dectect this by tagging DAR with 0x00f0
at every exception exit that modifies DAR.
Test for DAR=0x00f0 in DataTLBError and bail
to handle_page_fault().

Various kernel asm modifies SRR0/SRR1 just before executing
a rfi. If such code crosses a page boundary you risk a TLB miss
which will clobber SRR0/SRR1. Avoid this by always pinning
kernel instruction TLB space.

This is an assembler version to fixup DAR not being set
by dcbX, icbi instructions. There are two versions, one
uses selfmodifing code, the other uses a
jump table but is much bigger(default).

8xx has not had WRITETHRU due to lack of bits in the pte.
After the recent rewrite of the 8xx TLB code, there are
two bits left. Use one of them to WRITETHRU.
Perhaps use the last SW bit to PAGE_SPECIAL or PAGE_FILE?

There is no need to do set the DIRTY bit directly in DTLB Error.
Trap to do_page_fault() and let the generic MM code do the work.

Add basic support for the P4080 DS reference board. None of the data

Are you able to use a more recent kernel? A lot of work has gone into
SPI drivers in the last 5 releases
