Change to different macros for assembler macros since the old names in
powertv_setup.c were co-opted for use in asm/asm.h. This broken the
build for the powertv platform. This patch introduces new macros based on
the new macros in asm.h to take the place of the old macro values.

The sole user is au1xxx_calc_clock() which is only used in early bootup
where the is no paralellism thus no race condition to protect against.

The SmartMIPS ASE specifies how Read Inhibit (RI) and eXecute Inhibit
(XI) bits in the page tables work. The upper two bits of EntryLo{0,1}
are RI and XI when the feature is enabled in the PageGrain register.
SmartMIPS only covers 32-bit systems. Cavium Octeon+ extends this to
64-bit systems by continuing to place the RI and XI bits in the top of
EntryLo even when EntryLo is 64-bits wide.
Because we need to carry the RI and XI bits in the PTE, the layout of
the PTE is changed. There is a two instruction overhead in the TLB
refill hot path to get the EntryLo bits into the proper position.
Also the TLB load exception has to probe the TLB to check if RI or XI
caused the exception.
Also of note is that the layout of the PTE bits is done at compile and
runtime rather than statically. In the 32-bit case this allows for
the same number of PFN bits as before the patch as the _PAGE_HUGE is
not supported in 32-bit kernels (we have _PAGE_NO_EXEC and
_PAGE_NO_READ instead of _PAGE_READ and _PAGE_HUGE).
The patch is tested on Cavium Octeon+, but should also work on 32-bit
systems with the Smart-MIPS ASE.

64-bit CPUs have 64-bit c0_entrylo{0,1} registers. We should use the
64-bit dmtc0 instruction to set them. This becomes important if we
want to set the RI and XI bits present in some processors.

This patch adds a new DEBUG_ZBOOT option to allow the users to enable it
to debug the compressed kernel support for a new board and this optoin
should be disabled to reduce the kernel image size and speed up the
kernel booting procedure when the compressed kernel support is stable.

The userspace runtime linker uses the elf_platform to find the libraries
optimized for the current CPU archecture variant. First we need to allow it
to be set to something other than NULL. Follow-on patches will set some
values for specific CPUs.
GLIBC already does the right thing. The kernel just needs to supply good
data.

Although the hardware supports a 4/8bit SD interface and the driver
unconditionally advertises all hardware caps to the MMC core, not all
datalines may actually be wired up. This patch introduces another
field to au1xmmc platform data allowing platforms to disable certain
advanced host controller features.

AR7 has a larger physical offset than other MIPS based systems and therefore
needs to setup its handlers beyond the usual KSEG0 range. When running the
kernel in mapped mode this modification is also required. Remove function
comment which is now incorrect.
