[PATCH v2 2/2] ARM: setup_c: avoid clearing BSS twice

[David Picard]

Hi,

I would like this patches be reverted, since, despite the proposed 
fixes, it prevents the board arch/arm/boards/enclustra-sa2 to boot.

With the option CONFIG_DEBUG_LL enabled, the output is:

lowlevel init done
SDRAM setup...
SDRAM calibration...
done

Then, it hangs.

David
