2 Changes since U-Boot 0.2.0:
3 ======================================================================
5 * Add single quote support for (old) command line parser

15 Add i2c commands to PM826 config
17 * extend I2C POST code: check for list on known addresses
19 * Improve log buffer code; use "loglevel" to decide which messages
20 to log on the console, too (like in Linux); get rid of "logstart"

87 * Patch by Jim Sandoz, 07 Nov 2002:
88 Increase number of network RX buffers (PKTBUFSRX in
89 "include/net.h") for EEPRO100 based boards (especially SP8240)
90 which showed "Receiver is not ready" errors when U-Boot was
91 processing the receive buffers slower than the network controller
94 * Patch by Andreas Oberritter, 09 Nov 2002:
95 Change behaviour of NetLoop(): return -1 for errors, filesize
96 otherwise; return code 0 is valid an means no file loaded - in this
97 case the environment still gets updated!
99 * Patches by Jon Diekema, 9 Nov 2002:
100 - improve ADC/DAC clocking on the SACSng board to align
