76 (figuration of the utility, using a config file)
78 * Add single quote support for (old) command line parser
80 * Switch LWMON board default config from FRAM to EEPROM;
81 in POST, EEPROM shows up on 8 addresses
83 ======================================================================

90 * extend I2C POST code: check for list on known addresses
92 * Improve log buffer code; use "loglevel" to decide which messages
93 to log on the console, too (like in Linux); get rid of "logstart"
95 * Add command line tool to access the U-Boot's environment
96 (board-specific for TRAB now, to be fixed later)

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