Subject: * 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
