102
wdenk6dd652f2003-06-19 23:40:20 +0000103* Patches by Murray Jensen, 17 Jun 2003:
104 - Hymod board database mods: add "who" field and new xilinx chip types
105 - provide new "init_cmd_timeout()" function so code external to
106 "common/main.c" can use the "reset_cmd_timeout()" function before
107 entering the main loop
108 - add DTT support for adm1021 (new file dtt/adm1021.c; config
109 slightly different. see include/configs/hymod.h for an example
110 (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and
111 CFG_DTT_ADM1021 defined)
112 - add new "eeprom_probe()" function which has similar args and
113 behaves in a similar way to "eeprom_read()" etc.
114 - add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
115 function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
116 - gdbtools copyright update
117 - ensure that set_msr() executes the "sync" and "isync" instructions
118 after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
119 - 8260 I/O ports fix: Open Drain should be set last when configuring
120 - add SIU IRQ defines for 8260
121 - allow LDSCRIPT override and OBJCFLAGS initialization: change to
122 config.mk to allow board configurations to override the GNU
123 linker script, selected via the LDSCRIPT, make variable, and to
124 give an initial value to the OBJCFLAGS make variable
125 - 8260 i2c enhancement:
126 o correctly extends the timeout depending on the size of all
127 queued messages for both transmit and receive
128 o will not continue with receive if transmit times out
129 o ensures that the error callback is done for all queued tx
130 and rx messages
131 o correctly detects both tx and rx timeouts, only delivers one to
132 the callback, and does not overwrite an earlier error
133 o logic in i2c_probe now correct
134 - add "vprintf()" function so that "panic()" function can be
135 technically correct
136 - many Hymod board changes
137

wdenk4a6fd342003-04-12 23:38:12 +0000398 Changed DHCP client to use IP address from server option field #54
