src/sys/dev/eisa: ahbreg.h
Log Message:
Correct the comment about the INTHIGH bit in the INTDEF register. It
does indeed mean "IRQ signal is active-high", but "else edge" is not
correct; level-triggered EISA interrupt are active-low, and edge-triggered
EISA interrupts are rising-edge, so INTHIGH would in fact mean "edge".
