73 - 8260 i2c enhancement:
74 o correctly extends the timeout depending on the size of all
75 queued messages for both transmit and receive
76 o will not continue with receive if transmit times out
77 o ensures that the error callback is done for all queued tx
79 o correctly detects both tx and rx timeouts, only delivers one to
80 the callback, and does not overwrite an earlier error
81 o logic in i2c_probe now correct

637 (so far only 8xx -- needed on LWMON with 100ms watchdog)
639 * Improve command line tool to access the U-Boot's environment
640 (figuration of the utility, using a config file)
642 * Add single quote support for (old) command line parser

725 Increase number of network RX buffers (PKTBUFSRX in
726 "include/net.h") for EEPRO100 based boards (especially SP8240)
727 which showed "Receiver is not ready" errors when U-Boot was
728 processing the receive buffers slower than the network controller
731 * Patch by Andreas Oberritter, 09 Nov 2002:
732 Change behaviour of NetLoop(): return -1 for errors, filesize
733 otherwise; return code 0 is valid an means no file loaded - in this
734 case the environment still gets updated!
