 632   - Hymod board database mods: add "who" field and new xilinx chip types
 633   - provide new "init_cmd_timeout()" function so code external to
 634     "common/main.c" can use the "reset_cmd_timeout()" function before
 635     entering the main loop
 636   - add DTT support for adm1021 (new file dtt/adm1021.c; config
 637     slightly different. see include/configs/hymod.h for an example
 638     (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
 639     CFG_DTT_ADM1021 defined)
 640   - add new "eeprom_probe()" function which has similar args and
 641     behaves in a similar way to "eeprom_read()" etc.
 642   - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
 643     function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
 644   - gdbtools copyright update
 645   - ensure that set_msr() executes the "sync" and "isync" instructions
 646     after the "mtmsr" instruction in cpu/mpc8260/interrupts.c

 648   - add SIU IRQ defines for 8260
 649   - allow LDSCRIPT override and OBJCFLAGS initialization: change to
 650     config.mk to allow board configurations to override the GNU
 651     linker script, selected via the LDSCRIPT, make variable, and to
 652     give an initial value to the OBJCFLAGS make variable
 653   - 8260 i2c enhancement:
 654     o correctly extends the timeout depending on the size of all
 655       queued messages for both transmit and receive
 656     o will not continue with receive if transmit times out
 657     o ensures that the error callback is done for all queued tx
 658       and rx messages
 659     o correctly detects both tx and rx timeouts, only delivers one to
 660       the callback, and does not overwrite an earlier error
 661     o logic in i2c_probe now correct
 662   - add "vprintf()" function so that "panic()" function can be
 663     technically correct
 664   - many Hymod board changes
