wdenk6dd652f2003-06-19 23:40:20 +00005* Patches by Murray Jensen, 17 Jun 2003:
6 - Hymod board database mods: add "who" field and new xilinx chip types
7 - provide new "init_cmd_timeout()" function so code external to
8 "common/main.c" can use the "reset_cmd_timeout()" function before
9 entering the main loop
10 - add DTT support for adm1021 (new file dtt/adm1021.c; config
11 slightly different. see include/configs/hymod.h for an example
12 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
13 CFG_DTT_ADM1021 defined)
14 - add new "eeprom_probe()" function which has similar args and
15 behaves in a similar way to "eeprom_read()" etc.
16 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
17 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
18 - gdbtools copyright update
19 - ensure that set_msr() executes the "sync" and "isync" instructions
20 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
21 - 8260 I/O ports fix: Open Drain should be set last when configuring
22 - add SIU IRQ defines for 8260
23 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
24 config.mk to allow board configurations to override the GNU
25 linker script, selected via the LDSCRIPT, make variable, and to
26 give an initial value to the OBJCFLAGS make variable
27 - 8260 i2c enhancement:
28 o correctly extends the timeout depending on the size of all
29 queued messages for both transmit and receive
30 o will not continue with receive if transmit times out
31 o ensures that the error callback is done for all queued tx
32 and rx messages
33 o correctly detects both tx and rx timeouts, only delivers one to
34 the callback, and does not overwrite an earlier error
35 o logic in i2c_probe now correct
36 - add "vprintf()" function so that "panic()" function can be
37 technically correct
38 - many Hymod board changes
39

433 in short file reads.
434 - data copying now optionally takes fragment version numbers into
435 account, to avoid copying from older data.
436 See doc/README.JFFS2 for details.
