wdenk6dd652f2003-06-19 23:40:20 +0000840* Patches by Murray Jensen, 17 Jun 2003:
841 - Hymod board database mods: add "who" field and new xilinx chip types
842 - provide new "init_cmd_timeout()" function so code external to
843 "common/main.c" can use the "reset_cmd_timeout()" function before
844 entering the main loop
845 - add DTT support for adm1021 (new file dtt/adm1021.c; config
846 slightly different. see include/configs/hymod.h for an example
847 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
848 CFG_DTT_ADM1021 defined)
849 - add new "eeprom_probe()" function which has similar args and
850 behaves in a similar way to "eeprom_read()" etc.
851 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
852 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
853 - gdbtools copyright update
854 - ensure that set_msr() executes the "sync" and "isync" instructions
855 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
856 - 8260 I/O ports fix: Open Drain should be set last when configuring
857 - add SIU IRQ defines for 8260
858 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
859 config.mk to allow board configurations to override the GNU
860 linker script, selected via the LDSCRIPT, make variable, and to
861 give an initial value to the OBJCFLAGS make variable
862 - 8260 i2c enhancement:
863 o correctly extends the timeout depending on the size of all
864 queued messages for both transmit and receive
865 o will not continue with receive if transmit times out
866 o ensures that the error callback is done for all queued tx
867 and rx messages
868 o correctly detects both tx and rx timeouts, only delivers one to
869 the callback, and does not overwrite an earlier error
870 o logic in i2c_probe now correct
871 - add "vprintf()" function so that "panic()" function can be
872 technically correct
873 - many Hymod board changes
874

1010 fix calculation of base address in pci_hose_config_device()
1011
1012* Fix bug in command line parsing: "cmd1;cmd2" is supposed to always
