ARM: fix warning: target CPU does not support interworking
This patch fixes warnings like this:
start.S:0: warning: target CPU does not support interworking
which come from some ARM cross compilers and are caused by hard-coded
(with "--with-cpu=arm9" configuration option) ARM targets (which
support ARM Thumb instructions), while the ARM target selected from
the command line (with "-march=armv4") doesn't support Thumb
instructions.
This warning is issued by the compiler regardless of the real use of
the Thumb instructions in code.
To fix this problem, we use options according to compiler version
being used.

Prevent crash if random DTB address is passed to bootm
This patch adds bootm_start() return value check. If
error status is returned, we do not proceed further to
prevent board reset or crash as we still can recover
at this point.
Some of multi-function USB controllers (e.g. ISP1562) allow root hub
resetting only via EHCI registers. So, this patch adds the
corresponding kind of reset to OHCI's hc_reset() if the newly
introduced CONFIG_PCI_EHCI_DEVNO option is set (e.g. for Socrates
board).

devices: Use list_add_tail() instead of list_add() to register a device
This patch fixes a problem spotted on Glacier/Canyonlands (and most
likely lots of other board ports), that no serial output was seen
after console initialization in console_init_r(). This is because the
last added console device was used instead of the first added.
This patch fixes this problem by using list_add_tail() instead of
list_add() to register a device. This way the first added console
is used again.

mpc83xx: Store and display Arbiter Event Register values
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.

MPC83XX: Fix GPIO configuration - set gpio level before direction
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.

Add pixis_set_sgmii command
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 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
