Hi John,

Le 28/12/2010 01:33, John Rigby a ?crit :
> As implemented now the timer used to implement __udelay counts
> to 0xffffffff and then gets stuck there because the the programmed
> reload value is 0xffffffff.  This value is not only wrong but
> illegal according to the reference manual.

> One can reproduce the bug by leaving a board at the u-boot prompt

> forever.
>
> The timer is a count up timer that reloads as it rolls over
> from 0xffffffff so the correct load value is 0.
>
> Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
> a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.
