The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell based
machines a fault occurs causing a MCA. This patch moves the check
after mmu_context_init so the TLB and VHPT are properly setup.

The information in MCA records is filled in slightly differently on
Montecito than on Madison/McKinley.  Usually, the cache check and bus
check target identifiers have the same address.   On Montecito the
cache check and bus check target identifiers can be different if 
a corrected error (ie SBE or unconsumed poison data) was encountered and
then an uncorrected error (ie DBE) was consumed.  In that case, the 
cache check target identifier is the physical address of the DBE (that
caused the MCA to surface) while the bus check target identifier is the 
physical address of the SBE.  This patch correctly finds the target
identifier that triggered the MCA.

If there are multiple valid cache target identifiers in the same
error record then use the one with the lowest cache level.

Doug Leith observed a discrepancy between the version of CUBIC described
in the papers and the version in 2.6.18. A math error related to scaling
causes Cubic to grow too slowly.

Patch is from "Sangtae Ha" <sha2@ncsu.edu>. I validated that
it does fix the problems.

1) probe_other_fhcs() wants to see only non-central FHC
   busses, so skip FHCs that don't sit off the root

2) Like SBUS, FHC can lack the appropriate address and
   size cell count properties, so add an of_busses[]
   entry and handlers for that.

3) Central FHC irq translator probing was buggy.  We
   were trying to use dp->child in irq_trans_init but
   that linkage is not setup at this point.

   So instead, pass in the parent of "dp" and look for
   the child "fhc" with parent "central".

down these problems and testing out these fixes.

The read[bwl] and write[bwl] functions are meant for accessing PCI
devices. How this is achieved on AVR32 is unknown, as there are no
systems with a PCI bridge available yet.

On-chip peripheral access, however, should not depend on how we end
up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl]
is the right thing to do for on-chip peripherals. This patch converts
the drivers for the static memory controller, interrupt controller,
PIO controller and system manager to use __raw MMIO access.

A number of new drivers require io{read,write}{8,16,32}{be,} family of io
operations.  These are provided for the AVR32 by this patch in the form of
a series of macros.

Access to the (memory mapped) io space through these macros is defined to
be little endian only as little endian devices (such as PCI) are the main
consumer of IO access.  If high speed access is required,
io{read,write}{16,32}be macros are supplied to perform native big endian
access to this io space.

When calling e.g. atomic_sub_return with a large constant, the
compiler may output an immediate that is too large for the sub
instruction in the middle of the loop.

Fix this by explicitly specifying the number of bits allowed in the
constraint. Also stop atomic_add_return() and friends from falling
back to their respective "sub" variants if the constant is too large
to fit in an immediate.

Whenever an external device is resetted we really have to take
care to keep the channel in sync. Just notifying SCSI-ML and retry
is not enough as we have to make sure the SCSI bus is not getting
confused, either.
So whenever we detect an external reset we rewrite the command to
TUR, disable packetized command and notify the internal engine
that an abort has happened. This way we trigger a proper bus
reset sequence and all devices will be renegotiated properly.
Kudos to Justin Gibbs and Luben Tuikov for this idea.
