The patch was already merged, but I was able to reproduce this problem
and fixed in in the u-boot build file, can you please test the patch
which I sent separately. Please check if the u-boot generated by LEDE
will still work.

This activates neon and VFPv4 support for this target. The CPU support
these feature so also use them.

I do not have the hardware, could some please test if this still works
on a at91 compatible board.
