[U-Boot] Veyron-speedy u-boot

Hi Simon,

I've tried porting u-boot to the veyron-speedy Chromebook, based upon the veyron-minnie patch.

I've attached a patch with my changes to this email.

However, when I boot, all I get is a black screen. So, I have some questions:

1. Does u-boot show output to the laptop's screen, or do I have to make a serial console? 2. If I have to make a serial console, where do I do this/what is the pin layout? 3. Do I just have to sign u-boot-dtb.img with vbutil_kernel before dd-ing it onto a USB, or do I have to do something else to make the right image?

Yours thankfully,

Riley Baird
