1 ======================================================================
2 Changes since U-Boot 0.2.0:
3 ======================================================================
5 * Add support for V37 board
6 (patch by Jón Benediktsson, 11 Dec 2002)
8 * Update baudrate in bd_info when it gets changed
10 * Add watchdog trigger points while waiting for serial port
11 (so far only 8xx -- needed on LWMON with 100ms watchdog)
13 * Improve command line tool to access the U-Boot's environment
14 (figuration of the utility, using a config file)
16 * Add single quote support for (old) command line parser
18 * Switch LWMON board default config from FRAM to EEPROM;
19 in POST, EEPROM shows up on 8 addresses
21 ======================================================================
22 Changes for U-Boot 0.2.0:
23 ======================================================================
25 * Use 1-byte-read instead of -write for iprobe() function
26 Add i2c commands to PM826 config
28 * extend I2C POST code: check for list on known addresses
30 * Improve log buffer code; use "loglevel" to decide which messages
31 to log on the console, too (like in Linux); get rid of "logstart"
33 * Add command line tool to access the U-Boot's environment
34 (board-specific for TRAB now, to be fixed later)

81 Add code for AmigaOne board
82 (preliminary merge to U-Boot, still WIP)
84 * Patch by Jon Diekema, 12 Nov 2002:
85 - Adding URL for IEEE OUI lookup
86 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
88 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
89 root-on-nfs macros are designed to switch how the default boot
92 * Patch by Daniel Engström, 13 Nov 2002:
93 Add support for i386 architecture and AMD SC520 board
95 * Patch by Pierre Aubert, 12 Nov 2002:
96 Add support for DOS filesystem and booting from DOS floppy disk
98 * Patch by Jim Sandoz, 07 Nov 2002:
99 Increase number of network RX buffers (PKTBUFSRX in
100 "include/net.h") for EEPRO100 based boards (especially SP8240)
101 which showed "Receiver is not ready" errors when U-Boot was
102 processing the receive buffers slower than the network controller
105 * Patch by Andreas Oberritter, 09 Nov 2002:
106 Change behaviour of NetLoop(): return -1 for errors, filesize
107 otherwise; return code 0 is valid an means no file loaded - in this
108 case the environment still gets updated!
110 * Patches by Jon Diekema, 9 Nov 2002:
111 - improve ADC/DAC clocking on the SACSng board to align
112 the failing edges of LRCLK and SCLK
113 - sbc8260 configuration tweaks
114 - add status LED support for 82xx systems
115 - wire sspi/sspo commands into command handler; improved error
117 - add timestamp support and alternate memory test to the

121 Add "-n" to linker options to get rid of "Not enough room for
122 program headers" problem
124 * Patch by David Müller, 05 Nov 2002
125 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
126 so we can use an already existing name
128 * Patch by Pierre Aubert, 05 Nov 2002
129 Hardware relatied improvments in FDC boot code
131 * Patch by Holger Schurig, 5 Nov 2002:

137 * Fix uninitialized memory (MAC address) in 8xx SCC/FEC ethernet
140 * Add support for log buffer which can be passed to Linux kernel's
141 syslog mechanism; used especially for POST results.
143 * Patch by Klaus Heydeck, 31 Oct 2002:
144 Add initial support for kup4k board
146 * Patch by Robert Schwebel, 04 Nov 2002:
