- Add support for PPC440EPx & PPC440GRx
- Add support for PPC440EP(x)/GR(x) NAND controller
  in cpu/ppc4xx directory
- Add NAND boot functionality for Sequoia board,
  please see doc/README.nand-boot-ppc440 for details
- This Sequoia NAND image doesn't support environment
  in NAND for now. This will be added in a short while.
Patch by Stefan Roese, 07 Sep 2006

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

Also added Linux like BUG() macros.

Some code cleanup

Patch by Martin Krause, 20 Mar 2006

Signed-off-by: Martin Krause <martin.krause@tqs.de>

All MII configuration is done via FEC1 registers. But MII_SPEED was
configured according to FEC used. So if only FEC2 was used, this caused
the real MII_SPEED register in FEC1 to stay uninitalised, what lead
to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1
only.

This patch supports two serial consoles on boards with
a MPC5xxx CPU. The console can be switched at runtime
by setting stdin, stdout and stderr to the desired serial
interface (serial0 or serial1). The PSCs to be used as
console port are definded by CONFIG_PSC_CONSOLE
and CONFIG_PSC_CONSOLE2.
See README.serial_multi for details.

If the bus is blocked because of a previously interrupted
transfer, up to eleven clocks are generated on the I2CSCL
line to complete the transfer and to free the bus.
With this fix pin I2CSCL (PG6) is really configured as GPIO
so the clock pulses are really generated.

  -When booting from an epcs controller, the epcs bootrom may leave the
  slave select in an asserted state causing soft reset hang. This
  patch ensures slave select is negated at reset.

We use the "automatic" mode that was used for  the  MPC8266ADS  and
MPC8272 boards. Eventually this should be used on all boards?]

[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
 sufferes from licensing issues. Blame Intel.]
