wdenkb00ec162003-06-19 23:40:20 +0000598* Patches by Murray Jensen, 17 Jun 2003:
599 - Hymod board database mods: add "who" field and new xilinx chip types
600 - provide new "init_cmd_timeout()" function so code external to
601 "common/main.c" can use the "reset_cmd_timeout()" function before
602 entering the main loop
603 - add DTT support for adm1021 (new file dtt/adm1021.c; config
604 slightly different. see include/configs/hymod.h for an example
605 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
606 CFG_DTT_ADM1021 defined)
607 - add new "eeprom_probe()" function which has similar args and
608 behaves in a similar way to "eeprom_read()" etc.
609 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
610 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
611 - gdbtools copyright update
612 - ensure that set_msr() executes the "sync" and "isync" instructions
613 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
614 - 8260 I/O ports fix: Open Drain should be set last when configuring
615 - add SIU IRQ defines for 8260
616 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
617 config.mk to allow board configurations to override the GNU
618 linker script, selected via the LDSCRIPT, make variable, and to
619 give an initial value to the OBJCFLAGS make variable
620 - 8260 i2c enhancement:
621 o correctly extends the timeout depending on the size of all
622 queued messages for both transmit and receive
623 o will not continue with receive if transmit times out
624 o ensures that the error callback is done for all queued tx
625 and rx messages
626 o correctly detects both tx and rx timeouts, only delivers one to
627 the callback, and does not overwrite an earlier error
628 o logic in i2c_probe now correct
629 - add "vprintf()" function so that "panic()" function can be
630 technically correct
631 - many Hymod board changes

1184 (so far only 8xx -- needed on LWMON with 100ms watchdog)
1185
1186* Improve command line tool to access the U-Boot's environment
1187 (figuration of the utility, using a config file)

1205
1206* Add command line tool to access the U-Boot's environment
1207 (board-specific for TRAB now, to be fixed later)
