13 CONFIG_PCI_BOOTDELAY).
14 PCI spec 2.2 defines, that a pci target has 2^25 pci clocks after

22 * Add support for LXT971 PHY on PM826
24 * Patch by Tord Andersson, 16 Jan 2003:
25 Fix flash sector count for TQM8xxL
27 * Fix I2C EEPROM problem on ICU862 board (would only write the first
28 16 bytes out of each 32 byte block)
30 ======================================================================
31 Changes for U-Boot 0.2.1:
32 ======================================================================
34 * Add support for V37 board
35 (patch by Jón Benediktsson, 11 Dec 2002)
37 * Update baudrate in bd_info when it gets changed
39 * Add watchdog trigger points while waiting for serial port
40 (so far only 8xx -- needed on LWMON with 100ms watchdog)
42 * Improve command line tool to access the U-Boot's environment
43 (figuration of the utility, using a config file)
45 * Add single quote support for (old) command line parser
47 * Switch LWMON board default config from FRAM to EEPROM;
48 in POST, EEPROM shows up on 8 addresses
50 ======================================================================
51 Changes for U-Boot 0.2.0:
52 ======================================================================
54 * Use 1-byte-read instead of -write for iprobe() function
55 Add i2c commands to PM826 config
57 * extend I2C POST code: check for list on known addresses
59 * Improve log buffer code; use "loglevel" to decide which messages
60 to log on the console, too (like in Linux); get rid of "logstart"
62 * Add command line tool to access the U-Boot's environment
63 (board-specific for TRAB now, to be fixed later)

94 fix PCMCIA on MBX8xx board
96 * Patch by Pierre Aubert , 21 Nov 2002

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

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