This patch adds changes needed for Makalu rev 1.1:

- Enable 2nd DDR2 bank resulting in 256MByte of SDRAM
- Enable 2nd ethernet port EMAC1
- Use generic GPIO configuration framework (CFG_4xx_GPIO_TABLE)
- Reset PCIe ports via GPIO upon bootup

- Rename CFG_440_GPIO_TABLE to CFG_4xx_GPIO_TABLE
- Cleanup of the 4xx GPIO functions
- Move some GPIO defines from the cpu headers ppc405.h/ppc440.h into gpio.h

This patch disables the 44x d-cache on 'usb start' and
reenables it on 'usb stop'. This should be seen as a
temporary fix until the generic usb-ohci driver can
life with d-cache enabled.

Most 4xx PPC capable of using an I2C bootrom for bootstrap setting
already print a line with the information which I2C bootrom is
used for bootstrap configuration. So we don't need this extra line
with "I2C boot EEPROM en-/dis-abled".

This patch also has a little code cleanup integrated.

Since the cache handling functions were moved from start.S into cache.S

This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files
and to the Sequoia TLB init code. Now the cache can be enabled on 44x
boards by defining CONFIG_4xx_DCACHE in the board config file. This
option will disappear, when more boards use is successfully and no
more known problems exist.

This is tested successfully on Sequoia and Katmai. The only problem that
needs to be fixed is, that USB is not working on Sequoia right now, since
it will need some cache handling code too, similar to the 4xx EMAC driver.

Now with caches enabled (i- and d-cache) on 44x, we need a chance to
disable the cache for the CPU POST tests, since these tests consist
of self modifying code. This is done via the new change_tlb() function.

The Haleakala is nearly identical with the Kilauea eval board. The only
difference is that the 405EXr only supports one EMAC and one PCIe
interface. This patch adds support for the Haleakala board by using
the identical image for Kilauea and Haleakala. The distinction is done
by comparing the PVR.

This patch also adds a note to the fixed DDR setup for Bamboo NAND booting:

Note:
As found out by Eugene O'Brien <eugene.obrien@advantechamt.com>, the fixed
DDR setup has problems (U-Boot crashes randomly upon TFTP), when the DIMM
modules are still plugged in. So it is recommended to remove the DIMM
modules while using the NAND booting code with the fixed SDRAM setup!

Change all linker scripts to reference the changed driver name 4xx_uart.o.

This patch starts the rework of the PPC4xx serial driver. First we split
the file into two seperate files, one 4xx_uart.c with the 405/440 UART
handling code and the other one iop480_uart.c with the UART code for the
PLX-Tech IOP480 PPC (PPC403 based).

This patch adds support for the Xicor/Intersil X1205 RTC used on the
AMCC Makalu eval board. This driver is basically cloned from the Linux
driver version (2.6.23).

This patch also introduces the Linux bcd.h header for the BCD2BIN/
BIN2BCD conversions. In the future some of the other U-Boot RTC driver
should be converted to also use this header instead of implementing
their own local copy of these functions/macros.

This patch moves some common 4xx macros and the PPC405_SYS_INFO/

Lot's of other macros are good candidates to be consolidated this way
in the future.
