"revive" U-Boot support for old Motorola MPC860ADS board

* Patch by Cam(ilo?), 03 Dec 2003:
  make examples build even with broken Montavista objcopy

* Patch by Pavel Bartusek, 27 Nov 2003:
  fix conversion problem with "bootretry" evironment variable

* Make CONFIG_SILENT_CONSOLE work with CONFIG_AUTOBOOT_KEYED

for more information

* Patch by Brad Parker, 02 Aug 2003:
  fix sc520_cdp problems

* Implement Boot Cycle Detection (Req. 2.3 of OSDL CGL Reqirements)

* Allow erase command to cross flash bank boundaries

  - 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)

- Hymod board database mods: add "who" field and new xilinx chip types
- provide new "init_cmd_timeout()" function so code external to
  "common/main.c" can use the "reset_cmd_timeout()" function before
  entering the main loop
- add DTT support for adm1021 (new file dtt/adm1021.c; config
  slightly different. see include/configs/hymod.h for an example
  (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
  CFG_DTT_ADM1021 defined)
- add new "eeprom_probe()" function which has similar args and
  behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
  function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
  after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
  config.mk to allow board configurations to override the GNU
  linker script, selected via the LDSCRIPT, make variable, and to
  give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
  o correctly extends the timeout depending on the size of all
    queued messages for both transmit and receive
  o will not continue with receive if transmit times out
  o ensures that the error callback is done for all queued tx
    and rx messages
  o correctly detects both tx and rx timeouts, only delivers one to
    the callback, and does not overwrite an earlier error
  o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
  technically correct
- many Hymod board changes

* Fix alignment problems with flash driver for TRAB board

* Patch by Donald White, 21 May 2003:
  fix calculation of base address in pci_hose_config_device()

* Fix bug in command line parsing: "cmd1;cmd2" is supposed to always
  execute "cmd2", even if "cmd1" fails. Note that this is different
  to "run var1 var2" where the contents of "var2" will NOT be
  executed when a command in "var1" fails.

* 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

  Add IDMA example code (tested on 8260 only)

* Add support for MIPS64 5Kc CPUs

* Fix missing setting of "loadaddr" and "bootfile" on ARM and MIPS

* Patch by Denis Peter, 04 Apr 2003:
  - update MIP405-4 board

* Patches by Denis Peter, 03 April 2003:
  - fix PCI IRQs on MPL boards
  - fix two more un-relocated pointer problems

* Fix behaviour of "run" command:
  - print error message iv variable does not exist
  - terminate processing of arguments in case of error

* Patches by Peter Figuli, 10 Mar 2003
  - Add support for BTUART on PXA platform
  - Add support for WEP EP250 (PXA) board
