On some m32r platforms, cascaded ICUs are used. This patch is required to simplify ei_handler and consolidate platform- dependent ICU check routines. platform ICU/INT1 ICU/INT0 ICU/INT2 -------------- -------- -------- -------- m32104ut o - - m32700ut o o o opsput o o o usrv o - - (others) - - - Signed-off-by: Hitoshi Yamamoto <hitoshiy@linux-m32r.org> Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
