wdenkb00ec162003-06-19 23:40:20 +0000678* Patches by Murray Jensen, 17 Jun 2003:
679 - Hymod board database mods: add "who" field and new xilinx chip types
680 - provide new "init_cmd_timeout()" function so code external to
681 "common/main.c" can use the "reset_cmd_timeout()" function before
682 entering the main loop
683 - add DTT support for adm1021 (new file dtt/adm1021.c; config
684 slightly different. see include/configs/hymod.h for an example
685 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
686 CFG_DTT_ADM1021 defined)
687 - add new "eeprom_probe()" function which has similar args and
688 behaves in a similar way to "eeprom_read()" etc.
689 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
690 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
691 - gdbtools copyright update
692 - ensure that set_msr() executes the "sync" and "isync" instructions
693 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
694 - 8260 I/O ports fix: Open Drain should be set last when configuring
695 - add SIU IRQ defines for 8260
696 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
697 config.mk to allow board configurations to override the GNU
698 linker script, selected via the LDSCRIPT, make variable, and to
699 give an initial value to the OBJCFLAGS make variable
700 - 8260 i2c enhancement:
701 o correctly extends the timeout depending on the size of all
702 queued messages for both transmit and receive
703 o will not continue with receive if transmit times out
704 o ensures that the error callback is done for all queued tx
705 and rx messages
706 o correctly detects both tx and rx timeouts, only delivers one to
707 the callback, and does not overwrite an earlier error
708 o logic in i2c_probe now correct
709 - add "vprintf()" function so that "panic()" function can be
710 technically correct
711 - many Hymod board changes

wdenkb666c8f2003-03-06 00:58:30 +00001176 - Takes function pointer to function for reading the spd_nvram. Usefull
1177 for faking data or hardcode a module without the nvram.
1178 - fix other user for above change
1179 - fix some comments.
