1236 - provide new "init_cmd_timeout()" function so code external to
1237 "common/main.c" can use the "reset_cmd_timeout()" function before
1238 entering the main loop
1239 - add DTT support for adm1021 (new file dtt/adm1021.c; config
1240 slightly different. see include/configs/hymod.h for an example
1241 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
1242 CFG_DTT_ADM1021 defined)

1254 linker script, selected via the LDSCRIPT, make variable, and to
1255 give an initial value to the OBJCFLAGS make variable
1256 - 8260 i2c enhancement:
1257 o correctly extends the timeout depending on the size of all
1258 queued messages for both transmit and receive
1259 o will not continue with receive if transmit times out
1260 o ensures that the error callback is done for all queued tx
1262 o correctly detects both tx and rx timeouts, only delivers one to
1263 the callback, and does not overwrite an earlier error
1264 o logic in i2c_probe now correct
1265 - add "vprintf()" function so that "panic()" function can be
1267 - many Hymod board changes
