Since all the callers of the PHYS_TO_XKPHYS macro call with a constant,
put the cast to LL inside the macro where it really should be rather
than in all the callers. This makes macros like PHYS_TO_XKSEG_UNCACHED
work without gcc whining.

This complements the generic R4000/R4400 errata workaround code and adds
bits for the daddiu problem. In most places it just modifies handwritten
assembly code so that the assembler is allowed to use a temporary register
as daddiu may now be treated as a macro that expands to a sequence of li
and daddu. It is the AT register or, where AT is unavailable or used
explicitly for another purpose, an explicitly-named register is selected,
using the .set at=<reg> feature added recently to gas. This feature is
only used if CONFIG_CPU_DADDI_WORKAROUNDS has been set, so if the
workaround remains disabled, the required version of binutils stays
unchanged.
Similarly, daddiu instructions put in branch delay slots in noreorder
fragments are now taken out of them and the assembler is allowed to
reorder them itself as possible (which it does making the whole idea of
scheduling them into delay slots manually questionable).
Also in the very few places where such a simple conversion was not
possible, a handcoded longer sequence is implemented.
Other than that there are changes to code responsible for building the
TLB fault and page clear/copy handlers to avoid daddiu as appropriate.
These are only effective if the erratum is verified to be present at the
run time.
Finally there is a trivial update to __delay(), because it uses daddiu in
a branch delay slot.

This is the gereric part of R4000/R4400 errata workarounds. They include
compiler and assembler support as well as some source code modifications
to address the problems with some combinations of multiply/divide+shift
instructions as well as the daddi and daddiu instructions.
Changes included are as follows:
1. New Kconfig options to select workarounds by platforms as necessary.
2. Arch top-level Makefile to pass necessary options to the compiler; also
incompatible configurations are detected (-mno-sym32 unsupported as
horribly intrusive for little gain).
3. Bug detection updated and shuffled -- the multiply/divide+shift problem
is lethal enough that if not worked around it makes the kernel crash in
time_init() because of a division by zero; the daddiu erratum might
also trigger early potentially, though I have not observed it. On the
other hand the daddi detection code requires the exception subsystem to
have been initialised (and is there mainly for information).
4. r4k_daddiu_bug() added so that the existence of the erratum can be
queried by code at the run time as necessary; useful for generated code
like TLB fault and copy/clear page handlers.
5. __udelay() updated as it uses multiplication in inline assembly.
Note that -mdaddi requires modified toolchain (which has been maintained
by myself and available from my site for ~4years now -- versions covered
are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000
and -mfix-r4400 have been standard for a while though.

This patch converts the remaining 83xx boards to the dts-v1 format.
This includes the mpc8313_rdb, mpc832x_mds, mpc8323_rdb, mpc8349emitx,
mpc8349emitxgp and the mpc836x_mds.
The mpc8315_rdb mpc834x_mds, mpc837[789]_*, and sbc8349 were already
dts-v1 and only undergo minor changes for the sake of formatting
consistency across the whole group of boards; i.e. the idea being
that you can do a "diff -u board_A.dts board_B.dts" and see something
meaningful.
The general rule I've applied is that entries for values normally
parsed by humans are left in decimal (i.e. IRQ, cache size, clock
rates, basic counts and indexes) and all other data (i.e. reg and
ranges, IRQ flags etc.) remain in hex.
I've used dtc to confirm that the output prior to this changeset
matches the output after this changeset is applied for all boards.

Currently there are several dts that don't specify address or size
cells for the muram. This causes dtc to use default values, one of
which is an address-cells of two, and this breaks the parsing of the
muram ranges, which is assuming an address-cells of one. For example:
Warning (reg_format): "reg" property in
/qe@e0100000/muram@10000/data-only@0 has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 1)
Explicitly setting the address and size cells gets it parsed properly
and gets rid of the four dtc warnings.
