This patch prints the DDR status registers upon machine check
interrupt on the 440EPx/GRx. This can be useful especially when
ECC support is enabled.

I added some small changes to the original patch from Niklaus to
make it compile clean.

This patch removes the CFG_PCI_PRE_INIT option completely, since
it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.

This patch adds support for calling a plattform dependant
pci_pre_init() function for 405 boards. This can be used to
move the current pci_405gp_fixup_irq() function into the
board code.

This patch also makes the CFG_PCI_PRE_INIT define obsolete.
A default function with 'weak' attribute is used when
a board specific pci_pre_init() is not implemented.

A new environment variable, "logversion", selects the log buffer
behaviour. If it is not set or set to a value other than 2, then the
old, Linux 2.4.4, behaviour is selected.

The recently extended program_tlb() function had a problem when
multiple TLB's had to be setup (for example with 512MB of SDRAM). The
virtual address was not incremented. This patch fixes this issue
and is tested on Katmai with 512MB SDRAM.

This patch adds a board command to configure the I2C bootstrap EEPROM
values. Right now 533 and 667MHz are supported for booting either via NOR
or NAND FLASH. Here the usage:

=> bootstrap 533 nor        ;to configure the board for 533MHz NOR booting
=> bootstrap 667 nand       ;to configure the board for 667MHz NNAND booting
