Committed By: tsutsui

Modified Files:
src/sys/arch/amiga/dev: com_supio.c
Log Message:
Adjust sc_frequency in MD attachment as quirks.
It is not applicable to all 1665x variants.
XXX: It looks IOBlix board actually has 22.1184MHz OSC without clock divisor
http://amiga.resource.cx/photos/gallery/ioblix.jpg
so needs to investigate why we have to divide sc_frequency by four
to get right baud rate on IOBlix com. (firmware sets MCR_PRESCALE?)
