U-Boot for A64 git

[longsleep]

To make clear what Allwinner did to U-Boot I started a Git repository forked from mainline.

See https://github.com/longsleep/u-boot-pine64 

Branch pine64-hacks has applied the BSP changes on top of mainline 2014.07 tag and contains various required backports and fixes for Pine64 on top.

Disk image test releases for Pine64

I publish disk images which combine U-Boot, Kernel with a minimal initrd as base image for Linux distributions and for testing. **These images are for developers** and  are build with my set of Pine64 image building tools from here.
