This changeset revolves around the fact that all the SiS controllers have
the same enable bits, but differing cable detection methods. Previously
that meant each type had its own error_handler methods. Instead we can
now implement different ->cable_detect methods and share a single
error_handler which does the filtering by enable bits.
In addition we had some auto const arrays that should be static const. I'm
not sure if gcc already treats them intelligently but adding the static
will make sure.

2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.
Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the rest of the needed changes.
We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.
This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.
If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.
This patch simply adds the cable_detect method and helpers it doesn't use
them but other follow up patches will (ie Adrian please don't submit
patches to unexport them ;))

The chips covered by sata_mv have a 32-bit DMA boundary they must not
cross, not a 64K boundary. We are merely limited to a 64K maximum
segment size. Therefore, the DMA scatter/gather table fill code can be
greatly simplified, and we need not cut in half the S/G table size as
reported to the SCSI layer.
Also, the driver forget to turn on 64-bit DMA at the PCI layer. All
other data structures (both hardware and software) have been prepped for
64-bit PCI DMA. It was simply never turned on. <fingers crossed> let's
see if it still works...

I was going to say that eepro100's speedo_rx_link() does the same DMA
abuse as e100, but then I noticed one little detail: eepro100 sets both
EL (end of list) and S (suspend) bits in the RFD as it chains it to the
RFD list. e100 was only setting the EL bit. Hmmm, that's interesting.
That means that if HW reads a RFD with the S-bit set, it'll process
that RFD and then suspend the receive unit. The receive unit will
resume when SW clears the S-bit. There is no need for SW to restart
the receive unit. Which means a lot of the receive unit state tracking
code in the driver goes away.
So here's a patch against 2.6.14. (Sorry for inlining it; the mailer
I'm using now will mess with the word wrap). I can't test this on
XScale (unless someone has an e100 module for Gumstix :) . It should
be doing exactly what eepro100 does with RFDs. I don't believe this
change will introduce a performance hit because the S-bit and EL-bit go
hand-in-hand meaning if we're going to suspend because of the S- bit,
we're on the last resource anyway, so we'll have to wait for SW to
replenish.

The ucc_geth_memclean function can be called before the Tx BD rings, Rx
BD rings and associated socket buffers are allocated (for example if
ucc_fast_init fails). The current code doesn't check if p_tx_bd_ring[i]
is null, generating a kernel panic when trying to free the associated
socket buffers.
The function can also fail when accessing the uninitialized list_head
structures ugeth->group_hash_q and ugeth->ind_hash_q. In the current
implementation the list heads are initialized only when
maxGroupAddrInHash and maxIndAddrInHash are positive values, although I
think it's better to always initialize them.

Based partly on the gianfar driver, this patch fixes several
bugs which were causing NAPI to be completely unusable.
* An IRQ is still needed in NAPI, to kick off NAPI task,
and for Tx processing. Request the IRQ.
* If rx_work_limit = 0 we are not complete.
* While running Rx NAPI processing we must mask Rx events,
including Rx busy.
* ucc_geth_rx function does not need a lock.
Could lead to deadlock in NAPI case.
* There's no need to loop reading ucce multiple times in the ISR,
so while adding the call to schedule NAPI which was not there,
simplify the event processing into if-else format.
* Rx Busy now kicks off NAPI processing, while still
being counted as an error.

migrate ucc_geth to use the common phylib code.
There are several side effects from doing this:
o deprecate 'interface' property specification present
in some old device tree source files in
favour of a split 'max-speed' and 'interface-type'
description to appropriately match definitions
in include/linux/phy.h. Note that 'interface' property
is still honoured if max-speed or interface-type
are not present (backward compatible).
o compile-time CONFIG_UGETH_HAS_GIGA is eliminated
in favour of probe time speed derivation logic.
o adjust_link streamlined to only operate on maccfg2
and upsmr.r10m, instead of reapplying static initial
values related to the interface-type.
o Addition of UEC MDIO of_platform driver requires
platform code add 'mdio' type to id list
prior to calling of_platform_bus_probe (separate patch).
o ucc_struct_init introduced to reduce ucc_geth_startup
