3 ======================================================================
5 * Patch by Stefan Roese, 10 Feb 2003:
6 Add support for 4MB and 128MB onboard SDRAM (cpu/ppc4xx/sdram.c)
8 * Add dual ethernet support on PM826
10 * Add support for LXT971 PHY on PM826
12 * Patch by Tord Andersson, 16 Jan 2003:
13 Fix flash sector count for TQM8xxL
15 * Fix I2C EEPROM problem on ICU862 board (would only write the first
16 16 bytes out of each 32 byte block)
18 ======================================================================
19 Changes for U-Boot 0.2.1:
20 ======================================================================
22 * Add support for V37 board
23 (patch by Jón Benediktsson, 11 Dec 2002)
25 * Update baudrate in bd_info when it gets changed
27 * Add watchdog trigger points while waiting for serial port
28 (so far only 8xx -- needed on LWMON with 100ms watchdog)
30 * Improve command line tool to access the U-Boot's environment
31 (figuration of the utility, using a config file)
33 * Add single quote support for (old) command line parser
35 * Switch LWMON board default config from FRAM to EEPROM;
36 in POST, EEPROM shows up on 8 addresses
38 ======================================================================
39 Changes for U-Boot 0.2.0:
40 ======================================================================
42 * Use 1-byte-read instead of -write for iprobe() function
43 Add i2c commands to PM826 config
45 * extend I2C POST code: check for list on known addresses
47 * Improve log buffer code; use "loglevel" to decide which messages
48 to log on the console, too (like in Linux); get rid of "logstart"
50 * Add command line tool to access the U-Boot's environment
51 (board-specific for TRAB now, to be fixed later)

82 fix PCMCIA on MBX8xx board
84 * Patch by Pierre Aubert , 21 Nov 2002

99 (preliminary merge to U-Boot, still WIP)
101 * Patch by Jon Diekema, 12 Nov 2002:
102 - Adding URL for IEEE OUI lookup
103 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
105 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
106 root-on-nfs macros are designed to switch how the default boot
109 * Patch by Daniel Engström, 13 Nov 2002:
110 Add support for i386 architecture and AMD SC520 board
112 * Patch by Pierre Aubert, 12 Nov 2002:

115 * Patch by Jim Sandoz, 07 Nov 2002:
116 Increase number of network RX buffers (PKTBUFSRX in
117 "include/net.h") for EEPRO100 based boards (especially SP8240)
118 which showed "Receiver is not ready" errors when U-Boot was
119 processing the receive buffers slower than the network controller
122 * Patch by Andreas Oberritter, 09 Nov 2002:
123 Change behaviour of NetLoop(): return -1 for errors, filesize
124 otherwise; return code 0 is valid an means no file loaded - in this
125 case the environment still gets updated!
127 * Patches by Jon Diekema, 9 Nov 2002:
128 - improve ADC/DAC clocking on the SACSng board to align
129 the failing edges of LRCLK and SCLK
130 - sbc8260 configuration tweaks
131 - add status LED support for 82xx systems
132 - wire sspi/sspo commands into command handler; improved error
134 - add timestamp support and alternate memory test to the
137 * Patch by Vince Husovsky, 7 Nov 2002:
138 Add "-n" to linker options to get rid of "Not enough room for
139 program headers" problem
141 * Patch by David Müller, 05 Nov 2002
142 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
143 so we can use an already existing name
145 * Patch by Pierre Aubert, 05 Nov 2002
146 Hardware relatied improvments in FDC boot code
148 * Patch by Holger Schurig, 5 Nov 2002:

151 * Patch by Pierre Aubert, 05 Nov 2002
152 Add support for slave serial Spartan 2 FPGAs
154 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
157 * Add support for log buffer which can be passed to Linux kernel's
158 syslog mechanism; used especially for POST results.
160 * Patch by Klaus Heydeck, 31 Oct 2002:
161 Add initial support for kup4k board
163 * Patch by Robert Schwebel, 04 Nov 2002:
164 - use watchdog to reset PXA250 systems
165 - added progress callbacks to (some of the) ARM code
166 - update for Cogent CSB226 board
