vxWorks expects in
TLB 0 a entry for the Machine Check interrupt
TLB 1 a entry for the RAM
TLB 2 a entry for the EBC
TLB 3 a entry for the boot flash

After changing the baudrate to 9600 I had no problems to boot the
vxWorks image as distributed by WindRiver (Revision 2.0/1 from
June 18, 2007)

On Sequoia & LWMON5 the virtual address of the POST cache test is now
moved to a bigger address. This enables usage of more memory on those
boards.

Now the cpu node setup ("timebase-frequency" and "clock-frequency") is
without using the absolute path to the cpu node. This makes it possible
to use this U-Boot version with both versions of cpu-node naming
"cpu@0" and the former "PowerPC,440EPx@0".

When using dhcp/bootp the "netmask" environment variable is not

The BCSR status bit for the 66MHz PCI operation was correctly
addressed (MSB/LSB problem). Now the correct currently setup
PCI frequency is displayed upon bootup.

This patch also fixes this problem on Rainier & Yellowstone, since these
boards use the same souce code as Sequoia & Yosemite do.

The 440EPx has a problem when the PCI_CACHE_LINE_SIZE register is
set to non-zero, because it doesn't support MRM (memory-read-
multiple) correctly. We now added the possibility to configure
this register in the board config file, so that the default value
of 8 can be overridden.

Here the details of this patch:

o drivers_pci_auto.c: introduce CFG_PCI_CACHE_LINE_SIZE to allow
  board-specific settings. As an example the sequoia board requires 0.
  Idea from Stefan Roese <sr@denx.de>.
o board/amcc/sequoia/init.S: add a TLB mapping at 0xE8000000 for the
  PCI IO-space. Obtained from Stefan Roese <sr@denx.de>.
o include/configs/sequoia.h: turn CONFIG_PCI_PNP back on and set
  CFG_PCI_CACHE_LINE_SIZE to 0.

--

- Introduced dedicated switches for building 440 and 405 images required
  for 440-specific machine instructions like 'rfmci' etc.

- Exception vectors moved to the proper location (_start moved away from
  the critical exception handler space, which it occupied)

- CriticalInput now serviced (with default handler)

- MachineCheck properly serviced (added a dedicated handler and return
  subroutine)

- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
  unhandled and those not relevant for 4xx were eliminated)

- Eliminated Linux leftovers, removed dead code

The AMCC Secquoia board has been changed in a new revision from using a
33.000 MHz clock to a 33.333 MHz system clock. A bit in the CPLD
indicates the difference. This patch reads that bit and uses the correct
clock speed for the board. This code is backward compatable will all
prior boards. All prior boards will be read as 33.000.

When PCI PNP is enabled the pci pnp configuration routine is called
