* Patches by Yuli Barcohen, 13 Jul 2003:

- Correct flash and JFFS2 support for MPC8260ADS
  - fix PVR values and clock generation for PowerQUICC II family
    (8270/8275/8280)

* Patch by Bernhard Kuhn, 08 Jul 2003:
  - add support for M68K targets

* Patch by Ken Chou, 3 Jul:
  - Fix PCI config table for A3000
  - Fix iobase for natsemi.c
    (PCI_BASE_ADDRESS_0 is the IO base register for DP83815)

* Allow to enable "slow" POST routines by key press on power-on
* Fix temperature dependend switching of LCD backlight on LWMON
* Tweak output format for LWMON

* Clear Block Lock Bit, returns:
* 0 - OK
* 1 - Timeout
* Support for flash file system (JFFS2)
*
* We use custom partition info function because we have to fit the
* file system image between first sector (containing hard reset
* configuration word) and the sector containing U-Boot image. Standard
* partition info function does not allow for last sector specification
* and assumes that the file system occupies flash bank up to and
* including bank's last sector.
