U-Boot for Xilinx FPGA devices

In particular the Zynq and the Zed development board.

I didn't think I would go here, but I always do on every ARM based project at some point. U-boot code can been tough to navigate, but it often has extremely helpful code examples.

My interest started when I had questions related to writing some bare metal code to download bitstreams into the Zynq PL using the devcfg registers and the PCAP.

I interrupted the boot on my Ebaz board and looked at U-boot help, and by golly there is an fpga command.

Feedback? Questions? Drop me a line!
