Re: [U-Boot-Users] [PATCH][BUGFIX] Incorrect handling of AT91RM9200 timer overflow

Wolfgang,

the AT91RM9200 timer functions are confusing apples with bananas.

When the (16-bit) timer overflows, we have lost exactly 2^16 counts (or a multiple thereof, but we currently can't catch that situation), but get_timer_raw() instead adds the (unrelated) conversion factor to milliseconds, causing udelay() to potentially return too early.

The patch below fixes this.

Cheers Anders
