The ordering of accesses to the rx & tx descriptors is important, yet
the send & recv functions accessed them via regular structure accesses.
This leaves the compiler with the opportunity to reorder those accesses
or to hoist them outside of loops. Prevent that from happening by using
readl & writel to access the descriptors. As a nice bonus, this removes
the need for the driver to care about endianness.

The RX buffers are invalidated when a packet is received, however they
were not suitably cache-line aligned. Allocate them seperately to the
pcnet_priv structure and align to ARCH_DMA_MINALIGN in order to ensure
suitable alignment for the cache invalidation, preventing anything else
being placed in the same lines & lost.

The prior accesses to the descriptor rings & init block via cached
memory had a few issues:

  - The memory needs cache flushes or invalidation at the appropriate
    times, but was not necessarily aligned on cache line boundaries.
    This could lead to data being incorrectly lost or written back to
    RAM at the wrong time.

  - There are points where ordering of writes to the memory is
    important, but because it's cached memory the pcnet controller
    would see cache lines written back ordered by address. This could
    occasionally lead to hardware seeing descriptors in an incorrect
    state.

  - Flushing the cache constantly is inefficient.

So, to avoid all of those issues simply access the descriptors & init
block via uncached memory. The MIPS-specific UNCACHED_SDRAM macro is
used to do this (retrieving an address in kseg1) as I could see no
existing generic solution. Since the MIPS Malta board is the only user
of the pcnet driver, hopefully this doesn't matter.

Well written documentation for PMIC framework was missing and hence
it has been probably difficult and time consuming for other developers
to understand rationale for key design decisions and overall design
structure.

The show_model_r function should return an int but didn't. Return 0 to
indicate inevitable success and avoid the following if it is used:

common/board_r.c: In function 'show_model_r':
common/board_r.c:531:1: warning: no return statement in function returning non-void [-Wreturn-type]
 }

We should avoid the description in Makefile like this

ifdef CONFIG_FIT_SIGNATURE
hostprogs-y += fit_info$(SFX) fit_check_sign$(SFX)
endif

Otherwise, fit_info and fit_check_sign would never be cleaned
by "make clean".

This required moving it into a C file from the header.

The only user of a non-default name_to_gpio is blackfin, therefore build tested
with the blackfin bct-brettl2 build, which is one I picked at random. Also
tested with a build for the ARM tec board which uses the default/fallback
implementation. Inspection with objdump shows that both have done the right
thing.
