Patches by Murray Jensen, 17 Jun 2003:

- 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
