dcache_enable() and dcache_disable() will work reliably (after

Record the Arbiter Event Register values and optionally display them.
The Arbiter Event Register can record the type and effective address of
an arbiter error, even through an HRESET. This patch stores the values in
the global data structure.
Display of the Arbiter Event registers immediately after the RSR value
can be enabled with defines. The Arbiter values will only be displayed
if an arbiter event has occured since the last Power On Reset, and either
of the following defines exist:
#define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and
and type register values
#define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter
event register values
Address Only transactions are one of the trapped events that can register
as an arbiter event. They occur with some cache manipulation instructions
if the HID0_ABE (Address Broadcast Enable) is set and the memory region
has the MEMORY_COHERENCE WIMG bit set. Setting:
#define CONFIG_MASK_AER_AO - prevents the arbiter from recording address
only events, so that it can still capture
other real problems.

This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.
lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

Set DAT value before DIR values to avoid creating glitches on the
GPIO signals.
Set gpio level register before direction register to inhibit
glitches on high level output pins.
Dir and data gets cleared at powerup, so high level output lines see
a short low pulse between setting the direction and level registers.
Issue was seen on a new board with the nReset line of the NOR flash
connected to a GPIO. Setting the direction register puts the NOR flash
in reset so the next instruction to set the level cannot get executed.

The RSK7203 board has the SMSC9118 wired up 'incorrectly'.
Byte-swapping is necessary, and so poor performance is inevitable.
This problem cannot evade by the swap function of CHIP, this can
evade by software Byte-swapping.
And this has problem by FIFO access only. pkt_data_pull/pkt_data_push

The 8544DS and 8572DS platforms support an optional SGMII riser card to
expose ethernet over an SGMII interface. Once the card is in, it is also
necessary to configure the board such that it uses the card, rather than
the on-board ethernet ports. This can either be done by flipping dip switches
on the motherboard, or by modifying registers in the pixis. Either way
requires a reboot.
This adds a command to allow users to choose which ports are routed through
the SGMII card, and which through the onboard ports. It also allows users
to revert to the current switch settings.
This code does not work on the 8572, as the PIXIS is different.

The 8544DS and 8572DS systems have an optional SGMII riser card which
exposes new ethernet ports which are connected to the eTSECs via an
SGMII interface. The SGMII PHYs for this board are offset from the standard
PHY addresses, so this code modifies the passed in tsec_info structure to
use the SGMII PHYs on the card, instead.

The tsec driver contains a hard-coded array of configuration information
for the tsec ethernet controllers. We create a default function that works
for most tsecs, and allow that to be overridden by board code. It creates
an array of tsec_info structures, which are then parsed by the corresponding
driver instance to determine configuration. Also, add regs, miiregs, and
devname fields to the tsec_info structure, so that we don't need the kludgy
"index" parameter.
