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