Just to be clear, you are saying I should follow instructions from this, right?  https://github.com/pcm720/u-boot-build-scripts

No, his earlier, rockchip-based uboot has this command for writing to SPI:
Code:
sudo dd if=spiflash.bin of=/dev/mtd0
Looking at the build script of the most recent (your link,) that spiflash.bin will be in your build folder.
Ok.  Still seeking clarification as I'd really like this to work the first time.  1. Download and extract from https://github.com/pcm720/u-boot-build-scripts
2. Run build.sh
3. then run "sudo dd if=spiflash.bin of=/dev/mtd0

If this is already documented someplace, I apologize, but could you please point me in the right direction.  

Thanks!

First of all, to build the U-Boot on x32/x64 PC, you'll need to install aarch64-linux-gnu-gcc cross-compiler.
Then, clone the repository with "git clone --recursive", this will also clone ATF and U-Boot repositories as submodules.
After that, just build the U-Boot with build.sh and write spiflash.bin to /dev/mtd0 via dd.
