646 - Hymod board database mods: add "who" field and new xilinx chip types
647 - provide new "init_cmd_timeout()" function so code external to
648 "common/main.c" can use the "reset_cmd_timeout()" function before
649 entering the main loop
650 - add DTT support for adm1021 (new file dtt/adm1021.c; config
651 slightly different. see include/configs/hymod.h for an example
652 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
653 CFG_DTT_ADM1021 defined)
654 - add new "eeprom_probe()" function which has similar args and
655 behaves in a similar way to "eeprom_read()" etc.

657 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)

662 - add SIU IRQ defines for 8260
663 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
664 config.mk to allow board configurations to override the GNU
665 linker script, selected via the LDSCRIPT, make variable, and to
666 give an initial value to the OBJCFLAGS make variable
667 - 8260 i2c enhancement:
668 o correctly extends the timeout depending on the size of all
669 queued messages for both transmit and receive
670 o will not continue with receive if transmit times out
671 o ensures that the error callback is done for all queued tx
673 o correctly detects both tx and rx timeouts, only delivers one to
674 the callback, and does not overwrite an earlier error
675 o logic in i2c_probe now correct
676 - add "vprintf()" function so that "panic()" function can be
678 - many Hymod board changes

1219 16 bytes out of each 32 byte block)
1221 ======================================================================
1222 Changes for U-Boot 0.2.1:
1223 ======================================================================
1225 * Add support for V37 board
1226 (patch by Jón Benediktsson, 11 Dec 2002)
1228 * Update baudrate in bd_info when it gets changed
1230 * Add watchdog trigger points while waiting for serial port
1231 (so far only 8xx -- needed on LWMON with 100ms watchdog)
1233 * Improve command line tool to access the U-Boot's environment
1234 (figuration of the utility, using a config file)
1236 * Add single quote support for (old) command line parser
1238 * Switch LWMON board default config from FRAM to EEPROM;
1239 in POST, EEPROM shows up on 8 addresses
1241 ======================================================================
1242 Changes for U-Boot 0.2.0:
1243 ======================================================================

1246 Add i2c commands to PM826 config
1248 * extend I2C POST code: check for list on known addresses
1250 * Improve log buffer code; use "loglevel" to decide which messages
1251 to log on the console, too (like in Linux); get rid of "logstart"
1253 * Add command line tool to access the U-Boot's environment
1254 (board-specific for TRAB now, to be fixed later)

1302 (preliminary merge to U-Boot, still WIP)
1304 * Patch by Jon Diekema, 12 Nov 2002:
1305 - Adding URL for IEEE OUI lookup
1306 - Making the autoboot #defines dependent on CONFIG_AUTOBOOT_KEYED
1308 - In the CONFIG_EXTRA_ENV_SETTINGS #define, the root-on-initrd and
1309 root-on-nfs macros are designed to switch how the default boot
1310 method gets defined.

1319 Increase number of network RX buffers (PKTBUFSRX in
1320 "include/net.h") for EEPRO100 based boards (especially SP8240)
1321 which showed "Receiver is not ready" errors when U-Boot was
1322 processing the receive buffers slower than the network controller
1325 * Patch by Andreas Oberritter, 09 Nov 2002:
1326 Change behaviour of NetLoop(): return -1 for errors, filesize
1327 otherwise; return code 0 is valid an means no file loaded - in this
1328 case the environment still gets updated!

1338 SACSng configuration

1341 Add "-n" to linker options to get rid of "Not enough room for
1342 program headers" problem
1344 * Patch by David Müller, 05 Nov 2002
1345 Rename CONFIG_PLL_INPUT_FREQ to CONFIG_SYS_CLK_FREQ
