likely lots of other board ports), that no serial output was seen
after console initialization in console_init_r(). This is because the

This patch fixes this problem by using list_add_tail() instead of

mpc83xx: Store and display Arbiter Event Register values

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

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.

ARM: Add support for S3C6400 based SMDK6400 board

SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl
driver for it too. The board can also boot from the NOR flash, but due to
hardware limitations it can only address 64KiB on it, which is not enough
for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.

Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.
