get_cpu_board_revision() returned board revision based on information stored
in global static struct eeprom. It should instead use one from local struct
board_eeprom, to which the data is actually read from EEPROM. The bug led to
system hang after printing L1 cache information on U-Boot startup. The problem
was observed on MPC8555CDS system and possibly affects other Freescale MPC85xx
boards using CFG_I2C_EEPROM_CCID.
The change has been successfully tested on MPC8555CDS system.

The spd_dram code shifts the base address, then masks 20 bits, but
forgets to shift the base address back. Fix this by just masking the
base address correctly.
Found this bug while trying to relocate a DDR memory at the base != 0.

The new sys_eeprom.c supports both the old CCID EEPROM format and the new NXID
format, and so it obsoletes board/freescale/common/cds_eeprom.c. Freescale
86xx boards already use sys_eeprom.c, so this patch migrates the remaining
Freescale 85xx boards to use it as well. cds_eeprom.c is deleted.

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.

PCI I/O space is currently mapped 1:1 at 0xFA000000. Linux requires
PCI I/O space to start at 0 on the PCI bus. This patch maps PCI I/O
space such that 0xFA000000 in the processor's address space maps to 0
on the PCI I/O bus.

There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache. All callers of invalidate_l1_instruction_cache()
call icache_disable() right after. Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.
Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().

A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c

The recent change to move the .bss outside of the image gives older
binutils (ld from eldk4.1/binutils-2.16) some headache:
ppc_85xx-ld: u-boot: Not enough room for program headers (allocated 3, need 4)
ppc_85xx-ld: final link failed: Bad value
We workaround it by being explicit about the program headers and not
assigning the .bss to a program header.

* Move to using absolute addressing always. Makes the scripts a bit more
portable and common
* Moved .bss after the end of the image. These allows us to have more
room in the resulting binary image for code and data.
* Removed .text object files that aren't really needed
* Make sure _end is 4-byte aligned as the .bss init code expects this.
(Its possible that the end of .bss isn't 4-byte aligned)
