Added OCM test to POST layer. This version runs before all other tests
but doesn't yet interrupt post sequence on failure.

On LWMON5 we now use d-cache as init-ram and stack. The SPR POST test uses
self modifying code and this doesn't work with stack in d-cache, since
I can't move the code from d-cache to i-cache. We move the SPR test to
be executed a little later, after relocation. Then stack is located in
SDRAM and this self-modifying code is no problem anymore.

--

- Intracom board update.
- Add Codec POST.

  - add support for the Epson 156x series of graphical displays
    (These displays are serial and not suitable for using a normal
    framebuffer console on them)
  - add infrastructure needed in order to POST any DSPs in a board

  - 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

  - remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)

  - Splashscreen support
  - modem support
  - sysmon support
  - temperature dependend enabling of LCD

* Allow booting from old "PPCBoot" disk partitions

* Add support for TQM8255 Board / MPC8255 CPU

  to log on the console, too (like in Linux); get rid of "logstart"
