EBAZ4205 Bitcoin miner board - U-Boot

These notes go in two directions. One is learning about and fiddling with the Uboot that comes on the board I have received. The other is building U-Boot from source and then studing the sources. Someday perhaps I will know enough to be able to install a U-boot I have built onto my boards.

I'll note in passing that during this project I began and extended a scheme of using my connection to U-boot over a serial link as a remote protocol that I manipulate via Python scripts. This has been very useful and effective.

The U-boot on my board identifies itself as follows: 
1.0.0.47 (Dec 07 2017 - 00:36:15 +0800)

Model: Zynq Zed Development Board
DRAM:  ECC disabled 256 MiB
NAND:  128 MiB
MMC:   zynq_sdhci: 0
