1 ======================================================================
2 Changes since U-Boot 0.2.0:
3 ======================================================================
5 * Update baudrate in bd_info when it gets changed
7 * Add watchdog trigger points while waiting for serial port
8 (so far only 8xx -- needed on LWMON with 100ms watchdog)
10 * Improve command line tool to access the U-Boot's environment
11 (figuration of the utility, using a config file)
13 * Add single quote support for (old) command line parser
15 * Switch LWMON board default config from FRAM to EEPROM;
16 in POST, EEPROM shows up on 8 addresses
18 ======================================================================
19 Changes for U-Boot 0.2.0:
20 ======================================================================
22 * Use 1-byte-read instead of -write for iprobe() function
23 Add i2c commands to PM826 config
25 * extend I2C POST code: check for list on known addresses
27 * Improve log buffer code; use "loglevel" to decide which messages
28 to log on the console, too (like in Linux); get rid of "logstart"
30 * Add command line tool to access the U-Boot's environment
31 (board-specific for TRAB now, to be fixed later)
33 * Patch by Hans-Joerg Frieden, 06 Dec 2002

77 * Patch by Thomas Frieden, 13 Nov 2002:
78 Add code for AmigaOne board
79 (preliminary merge to U-Boot, still WIP)
81 * Patch by Jon Diekema, 12 Nov 2002:
82 - Adding URL for IEEE OUI lookup
83 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
85 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
86 root-on-nfs macros are designed to switch how the default boot
89 * Patch by Daniel Engström, 13 Nov 2002:
90 Add support for i386 architecture and AMD SC520 board
92 * Patch by Pierre Aubert, 12 Nov 2002:
93 Add support for DOS filesystem and booting from DOS floppy disk
95 * Patch by Jim Sandoz, 07 Nov 2002:
96 Increase number of network RX buffers (PKTBUFSRX in
97 "include/net.h") for EEPRO100 based boards (especially SP8240)
98 which showed "Receiver is not ready" errors when U-Boot was
99 processing the receive buffers slower than the network controller
102 * Patch by Andreas Oberritter, 09 Nov 2002:
103 Change behaviour of NetLoop(): return -1 for errors, filesize
104 otherwise; return code 0 is valid an means no file loaded - in this
105 case the environment still gets updated!
107 * Patches by Jon Diekema, 9 Nov 2002:
108 - improve ADC/DAC clocking on the SACSng board to align
109 the failing edges of LRCLK and SCLK
110 - sbc8260 configuration tweaks
111 - add status LED support for 82xx systems
112 - wire sspi/sspo commands into command handler; improved error
114 - add timestamp support and alternate memory test to the
117 * Patch by Vince Husovsky, 7 Nov 2002:
118 Add "-n" to linker options to get rid of "Not enough room for
119 program headers" problem
121 * Patch by David Müller, 05 Nov 2002
122 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
123 so we can use an already existing name
125 * Patch by Pierre Aubert, 05 Nov 2002
126 Hardware relatied improvments in FDC boot code
128 * Patch by Holger Schurig, 5 Nov 2002:
129 Make the PXA really change it's frequency

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