3======================================================================
4
wdenk0b97ab12003-06-19 23:58:30 +00005* * Patch by Richard Woodruff, 19 June 03:
6 - Fixed smc91c111 driver to sync with the u-boot environment (driver/smc91c111.c).

8
9* Patch by Ken Chou, 17 June 2003:
10 Added support for A3000 SBC board (Artis Microsystems Inc.)
11
wdenk6dd652f2003-06-19 23:40:20 +000012* Patches by Murray Jensen, 17 Jun 2003:
13 - Hymod board database mods: add "who" field and new xilinx chip types
14 - provide new "init_cmd_timeout()" function so code external to
15 "common/main.c" can use the "reset_cmd_timeout()" function before
16 entering the main loop
17 - add DTT support for adm1021 (new file dtt/adm1021.c; config
18 slightly different. see include/configs/hymod.h for an example
19 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
20 CFG_DTT_ADM1021 defined)
21 - add new "eeprom_probe()" function which has similar args and
22 behaves in a similar way to "eeprom_read()" etc.
23 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
24 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
25 - gdbtools copyright update
26 - ensure that set_msr() executes the "sync" and "isync" instructions
27 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
28 - 8260 I/O ports fix: Open Drain should be set last when configuring
29 - add SIU IRQ defines for 8260
30 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
31 config.mk to allow board configurations to override the GNU
32 linker script, selected via the LDSCRIPT, make variable, and to
33 give an initial value to the OBJCFLAGS make variable
34 - 8260 i2c enhancement:
35 o correctly extends the timeout depending on the size of all
36 queued messages for both transmit and receive
37 o will not continue with receive if transmit times out
38 o ensures that the error callback is done for all queued tx
39 and rx messages
40 o correctly detects both tx and rx timeouts, only delivers one to
41 the callback, and does not overwrite an earlier error
42 o logic in i2c_probe now correct
43 - add "vprintf()" function so that "panic()" function can be
44 technically correct
45 - many Hymod board changes
46
