1 ======================================================================
2 Changes since U-Boot 0.2.1:
3 ======================================================================
5 * Add dual ethernet support on PM826
7 * Add support for LXT971 PHY on PM826
9 * Patch by Tord Andersson, 16 Jan 2003:
10 Fix flash sector count for TQM8xxL
12 * Fix I2C EEPROM problem on ICU862 board (would only write the first
13 16 bytes out of each 32 byte block)
15 ======================================================================
16 Changes for U-Boot 0.2.1:
17 ======================================================================
19 * Add support for V37 board
20 (patch by Jón Benediktsson, 11 Dec 2002)
22 * Update baudrate in bd_info when it gets changed
24 * Add watchdog trigger points while waiting for serial port
25 (so far only 8xx -- needed on LWMON with 100ms watchdog)
27 * Improve command line tool to access the U-Boot's environment
28 (figuration of the utility, using a config file)
30 * Add single quote support for (old) command line parser
32 * Switch LWMON board default config from FRAM to EEPROM;
33 in POST, EEPROM shows up on 8 addresses
35 ======================================================================
36 Changes for U-Boot 0.2.0:
37 ======================================================================
39 * Use 1-byte-read instead of -write for iprobe() function
40 Add i2c commands to PM826 config
42 * extend I2C POST code: check for list on known addresses
44 * Improve log buffer code; use "loglevel" to decide which messages
45 to log on the console, too (like in Linux); get rid of "logstart"
47 * Add command line tool to access the U-Boot's environment
48 (board-specific for TRAB now, to be fixed later)

96 (preliminary merge to U-Boot, still WIP)
98 * Patch by Jon Diekema, 12 Nov 2002:
99 - Adding URL for IEEE OUI lookup
100 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
102 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
103 root-on-nfs macros are designed to switch how the default boot
106 * Patch by Daniel Engström, 13 Nov 2002:

109 * Patch by Pierre Aubert, 12 Nov 2002:

112 * Patch by Jim Sandoz, 07 Nov 2002:
113 Increase number of network RX buffers (PKTBUFSRX in
114 "include/net.h") for EEPRO100 based boards (especially SP8240)
115 which showed "Receiver is not ready" errors when U-Boot was
116 processing the receive buffers slower than the network controller
119 * Patch by Andreas Oberritter, 09 Nov 2002:
120 Change behaviour of NetLoop(): return -1 for errors, filesize
121 otherwise; return code 0 is valid an means no file loaded - in this
122 case the environment still gets updated!
124 * Patches by Jon Diekema, 9 Nov 2002:
125 - improve ADC/DAC clocking on the SACSng board to align
126 the failing edges of LRCLK and SCLK

136 program headers" problem
138 * Patch by David Müller, 05 Nov 2002
139 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
140 so we can use an already existing name
142 * Patch by Pierre Aubert, 05 Nov 2002
143 Hardware relatied improvments in FDC boot code
145 * Patch by Holger Schurig, 5 Nov 2002:

151 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
154 * Add support for log buffer which can be passed to Linux kernel's
155 syslog mechanism; used especially for POST results.

158 Add initial support for kup4k board
160 * Patch by Robert Schwebel, 04 Nov 2002:
