  Fix problem with only partially cleared .bss segment

* Patch by Rune Torgersen, 12 May 2003:
  get PCI to work on a MPC8266ADS board; incorporate change to
  cpu/mpc8260/pci.c to enable overrides of PCI memory parameters

allow to pass boot bitmap addresses in environment variables;
allow for zero boot delay

* Patch by Christian Geiinger, 19 May 2002:
  On TRAB: wait until the dummy byte has been completely sent

  update for CrayL1 board

* Patch by Pantelis Antoniou, 21 Apr 2003:
  add boot support for ARTOS (a proprietary OS)

* Patch by Steven Scholz, 11 Apr 2003:
  Add support for RTC DS1338

* Patch by Rod Boyce, 24 Jan 2003:
  Fix counting of extended partitions in diskboot command

allow the use of CFG_LOADS when CFG_NO_FLASH is set

(includes support for Intel 82365 and compatible PC Card controllers,
and Yenta-compatible PCI-to-CardBus controllers)

Add lan91c96 driver (tested on Lubbock and custom PXA250 board only)

* Patch by Keith Outwater, 28 Apr 2003:
  - Miscellaneous corrections and additions to GEN860T board specific code.
  - Added GEN860_SC variant to GEN860T.
  - Miscellaneous corrections to GEN860T documentation.
  - Correct duplicate entry in U-Boot CREDITS file.
  - Add GEN860T_SC entry in MAINTAINERS file.
  - Update CREDITS file with GEN860T_SC info.

* Update Smiths Aerospace addresses in MAINTAINERS file

* Fix error handling in hush's version of "run" command

  - 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

* MPC823 LCD driver: Fill color map backwards, to allow for steady
  display when Linux takes over

* Patch by Erwin Rol, 27 Feb 2003:
  Add support for RTEMS (this time for real).

* Add support for "bmp info" and "bmp display" commands to load
  bitmap images; this can be used (for example in a "preboot"
  command) to display a splash screen very quickly after poweron.

* Add support for 133 MHz clock on INCA-IP board

  Update for R360MPI board

* Add new meaning to "autostart" environment variable:
  If set to "no", a standalone image passed to the
  "bootm" command will be copied to the load address
  (and eventually uncompressed), but NOT be started.
  This can be used to load and uncompress arbitrary
  data.

* Set max brightness for MN11236 displays on TRAB board
