U-Boot v2 aka Barebox

Hi Franck,

Email send. Thanks.

On another side, I face a new trouble.

After fixing nios_sopc.h, barebox start, and I reach the prompt.

But shortly after, without notice, an exception is raised.

First, this never happen with our previous MPU design.

Second, It don't seems to occur when I "place" barebox at bottom of DDR3 (above 0xc8000000).

Third, instruction @ XXXX is random.

I give a look at nios2/lib/clock.c, and everything seems Ok. But I notice important side effect when I try some minor change on this file.

Linux kernel still running nicely.

Christophe
