wdenk6dd652f2003-06-19 23:40:20 +000034* Patches by Murray Jensen, 17 Jun 2003:
35 - Hymod board database mods: add "who" field and new xilinx chip types
36 - provide new "init_cmd_timeout()" function so code external to
37 "common/main.c" can use the "reset_cmd_timeout()" function before
38 entering the main loop
39 - add DTT support for adm1021 (new file dtt/adm1021.c; config
40 slightly different. see include/configs/hymod.h for an example
41 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
42 CFG_DTT_ADM1021 defined)
43 - add new "eeprom_probe()" function which has similar args and
44 behaves in a similar way to "eeprom_read()" etc.
45 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
46 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
47 - gdbtools copyright update
48 - ensure that set_msr() executes the "sync" and "isync" instructions
49 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
50 - 8260 I/O ports fix: Open Drain should be set last when configuring
51 - add SIU IRQ defines for 8260
52 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
53 config.mk to allow board configurations to override the GNU
54 linker script, selected via the LDSCRIPT, make variable, and to
55 give an initial value to the OBJCFLAGS make variable
56 - 8260 i2c enhancement:
57 o correctly extends the timeout depending on the size of all
58 queued messages for both transmit and receive
59 o will not continue with receive if transmit times out
60 o ensures that the error callback is done for all queued tx
61 and rx messages
62 o correctly detects both tx and rx timeouts, only delivers one to
63 the callback, and does not overwrite an earlier error
64 o logic in i2c_probe now correct
65 - add "vprintf()" function so that "panic()" function can be
66 technically correct
67 - many Hymod board changes
68
