arm: timer and interrupt init rework 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> 2009-05-15 21:47:02 +00:00			`int timer_init (void)`

ARM: add tegra20 support to arm720t Add support for tegra20 arm7 boot processor. This processor is used to power on the Cortex A9 and transfer control to it. In tegra this processor is an ARM7TDMI not an ARM720T, but since we don't use cache it was easier to just reuse the ARM720T code as the processors are otherwise identical except for cache and MMU.
