net: pcnet: Fix init on big endian 64 bit

If dev->iobase is 64 bits wide then writing the value of the BAR into a
pointer to iobase will not work on big endian systems, where the BAR
value will incorrectly get written to the upper 32 bits of the 64 bit
variable. Fix this by reading the BAR into a u32, matching the type
expected by pci_read_config_dword.

net: pcnet: refactor mapping of virtual addresses to physical ones

pci_virt_to_mem() uses virt_to_phys() to get the physical address.
But pci_virt_to_mem() is also called with uncached addresses which
is wrong according to the documentation of virt_to_phys().

Refactor the PCI_TO_MEM() macro to optionally map an uncached address
back to a cached one before calling pci_virt_to_mem().

Currently pcnet works because virt_to_phys() is incorrectly implemented
on MIPS. With the upcoming asm header file update for MIPS, the
virt_to_phys() implementation will be fixed. Thus this patch is needed
to keep pcnet working on MIPS Malta board.

net: cosmetic: Fix var naming net <-> eth drivers

Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.

This cleans up the temporary hacks that were added to this interface
along with the DM support.

This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).

pcnet: force ordering of descriptor accesses

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.

pcnet: align rx buffers for cache invalidation

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.

pcnet: access descriptor rings & init block uncached

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.

pcnet: enable the NOUFLO feature

On relatively slow boards (such as the MIPS Malta with an FPGA core
card) it can be extremely common for transmits to underflow - to the
point where it appears they simply do not work at all. Setting the
NOUFLO bit causes the ethernet controller to not begin transmission on
the wire until a transmit start point is reached. Setting that transmit
start point to the full packet will cause the controller to only
transmit the packet once it has buffered it entirely thus preventing any
transmit underflows from occuring and allowing the controller to
function on slower boards.

pcnet: add cache flushing & invalidation

Ensure that the view of memory from the CPU & the ethernet controller is
coherent at the various points where they exchange data. This prevents
stale data from being transmitted or received, and prevents the driver
from getting stuck waiting for the ethernet controller to update
descriptors when in reality it has but the old values are being read
from cache.
