80 give an initial value to the OBJCFLAGS make variable
81 - 8260 i2c enhancement:
82 o correctly extends the timeout depending on the size of all
83 queued messages for both transmit and receive
84 o will not continue with receive if transmit times out
85 o ensures that the error callback is done for all queued tx
87 o correctly detects both tx and rx timeouts, only delivers one to
88 the callback, and does not overwrite an earlier error
89 o logic in i2c_probe now correct

648 (figuration of the utility, using a config file)
650 * Add single quote support for (old) command line parser

735 which showed "Receiver is not ready" errors when U-Boot was
736 processing the receive buffers slower than the network controller
739 * Patch by Andreas Oberritter, 09 Nov 2002:
740 Change behaviour of NetLoop(): return -1 for errors, filesize
741 otherwise; return code 0 is valid an means no file loaded - in this
742 case the environment still gets updated!
