actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
