On 64bit systems the timer value might be truncated to a 32bit value causing malfunctions. For example on ARM the timer might start from 0 again only after a cold reset. The 32bit overflow occurs after a bit more than 49 days (1000 Hz counter) so booting after that time may lead to a surprise because the board might become stuck requiring a cold reset.

get_timer returns a ulong value representing system time in ms. On a 64-bit system, this ulong value is 64 bits long. However, the driver stores it in a 32-bit unsigned integer, which overflows after 49 days up time, causing the driver to get an incorrect time. Replace the unsigned int variable with a ulong type to properly store the value returned by get_timer. Signed-off-by: Stanley Chu <yschu@nuvoton.com>
