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

has the MEMORY_COHERENCE WIMG bit set. Setting:
 #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address

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.
