    "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

    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

  Cleanup & bug fixes for JFFS2 code:
  - the memory mangement was broken. It caused havoc on malloc by
    writing beyond the block boundaries.
  - the length calculation for files was wrong, sometimes resulting
    in short file reads.
  - data copying now optionally takes fragment version numbers into
    account, to avoid copying from older data.
  See doc/README.JFFS2 for details.

  processing the receive buffers slower than the network controller
  was filling them.
