[PATCH] ARM: footbridge rtc init (336eb02b) · Commits · 戴 / test

The footbridge ISA RTC was being initialised before we had setup the kernel timer. This caused a divide by zero error when the current time of day is set. Resolve this by initialising the RTC after the kernel timer has been initialised. Signed-off-by:
