Hi Peng,

Change type of timebase_l/h to unsigned int.
What is the motivation for this, please?
From lib/time.c: ((uint64_t)gd->timebase_h << 32) | gd->timebase_l;
This piece code is based on that timebase_h and timebase_l are 32bits width, I think. But unsigned long are 64bits width on ARM64. I am not sure, but I suppose same case on other archs.
Thanks, Peng.
