  - 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.

    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
