Realview/Versatile copied the Integrator timer code, including the calculations for ensuring that the reload value fits into the 16-bit counter. However, these platforms have a 32-bit counter which is clocked at a slower rate. The result is that the preprocessor conditions are never triggered: TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than 0x10000. So, remove the unnecessary complexity, reducing the TIMER_RELOAD calculation to just: TICKS_PER_uSEC * mSEC_10 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
