Allwinner A10 not boot directory by u-boot

[Mori Hiroki]

Hi

I try pcDuino by 13-CURRENT. This module use 
Allwinner A10.

I want boot directly by u-boot rather than ubldr.

I found stop in pmap_bootstrap_prepare(lastaddr) at initarm().

If you have Advice, Please let me know.

Thanks

Hiroki Mori
