On TI panda board, stay in u-boot and do nothing in 30 minutes, then
try to get mmc info or reset, u-boot will hang.
Bellow is the error log:
--

sounds like the core timer logic is broken for whatever omap part is on there

That is correct, once the timer reaches 0xFFFFFFFF it reloads with
0xFFFFFFFF and gets stuck there. I did a patch that was never
accepted late last year. On more careful consideration my patch was
also broken but in different ways.
