wdenk6dd652f2003-06-19 23:40:20 +000045* Patches by Murray Jensen, 17 Jun 2003:
46 - Hymod board database mods: add "who" field and new xilinx chip types
47 - provide new "init_cmd_timeout()" function so code external to
48 "common/main.c" can use the "reset_cmd_timeout()" function before
49 entering the main loop
50 - add DTT support for adm1021 (new file dtt/adm1021.c; config
51 slightly different. see include/configs/hymod.h for an example
52 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
53 CFG_DTT_ADM1021 defined)
54 - add new "eeprom_probe()" function which has similar args and
55 behaves in a similar way to "eeprom_read()" etc.
56 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
57 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
58 - gdbtools copyright update
59 - ensure that set_msr() executes the "sync" and "isync" instructions
60 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
61 - 8260 I/O ports fix: Open Drain should be set last when configuring
62 - add SIU IRQ defines for 8260
63 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
64 config.mk to allow board configurations to override the GNU
65 linker script, selected via the LDSCRIPT, make variable, and to
66 give an initial value to the OBJCFLAGS make variable
67 - 8260 i2c enhancement:
68 o correctly extends the timeout depending on the size of all
69 queued messages for both transmit and receive
70 o will not continue with receive if transmit times out
71 o ensures that the error callback is done for all queued tx
72 and rx messages
73 o correctly detects both tx and rx timeouts, only delivers one to
74 the callback, and does not overwrite an earlier error
75 o logic in i2c_probe now correct
76 - add "vprintf()" function so that "panic()" function can be
77 technically correct
78 - many Hymod board changes
79
