Does anyone know where I can find any u-boot based image for the Avaota A1?

Supposedly mainline u-boot supports the A527 chipset but I've never been able to get it to work if I build from scratch or find an image that has it as the boot loader.

I do not want Syterkit. I want a u-boot prompt that I can grab a kernel from a tftp server to boot.
