1 ======================================================================
2 Changes since U-Boot 0.2.1:
3 ======================================================================
5 * Patch by Stefan Roese, 13 Feb 2003:
6 Add "pcidelay" environment variable (in ms, enabled via
8 PCI spec 2.2 defines, that a pci target has 2^25 pci clocks after
9 RST# to respond to configuration cycles (33MHz -> 1s).
11 * Patch by Stefan Roese, 10 Feb 2003:
12 Add support for 4MB and 128MB onboard SDRAM (cpu/ppc4xx/sdram.c)
14 * Add dual ethernet support on PM826
16 * Add support for LXT971 PHY on PM826
18 * Patch by Tord Andersson, 16 Jan 2003:
19 Fix flash sector count for TQM8xxL
21 * Fix I2C EEPROM problem on ICU862 board (would only write the first
22 16 bytes out of each 32 byte block)
24 ======================================================================
25 Changes for U-Boot 0.2.1:
26 ======================================================================
28 * Add support for V37 board
29 (patch by Jón Benediktsson, 11 Dec 2002)
31 * Update baudrate in bd_info when it gets changed
33 * Add watchdog trigger points while waiting for serial port
34 (so far only 8xx -- needed on LWMON with 100ms watchdog)
36 * Improve command line tool to access the U-Boot's environment
37 (figuration of the utility, using a config file)
39 * Add single quote support for (old) command line parser
41 * Switch LWMON board default config from FRAM to EEPROM;
42 in POST, EEPROM shows up on 8 addresses
44 ======================================================================
45 Changes for U-Boot 0.2.0:
46 ======================================================================
48 * Use 1-byte-read instead of -write for iprobe() function
49 Add i2c commands to PM826 config
51 * extend I2C POST code: check for list on known addresses
53 * Improve log buffer code; use "loglevel" to decide which messages
54 to log on the console, too (like in Linux); get rid of "logstart"
56 * Add command line tool to access the U-Boot's environment
57 (board-specific for TRAB now, to be fixed later)

105 (preliminary merge to U-Boot, still WIP)
107 * Patch by Jon Diekema, 12 Nov 2002:
108 - Adding URL for IEEE OUI lookup
109 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
111 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
112 root-on-nfs macros are designed to switch how the default boot
115 * Patch by Daniel Engström, 13 Nov 2002:

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

145 program headers" problem
147 * Patch by David Müller, 05 Nov 2002
148 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ

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