New Revision: 2998
Removed:
trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/coherent_ht_car.c
Modified:
trunk/LinuxBIOSv2/src/mainboard/iwill/dk8_htx/cache_as_ram_auto.c
trunk/LinuxBIOSv2/src/mainboard/iwill/dk8s2/cache_as_ram_auto.c
trunk/LinuxBIOSv2/src/mainboard/iwill/dk8x/cache_as_ram_auto.c
Log:
Remove the coherent_ht_car.c file. It is exactly the same as
coherent_ht.c (save one empty line removed) so there's no use
to keep it around.
