I do not think there is any reason to use external hardware for flashing. The SPI flash can simply be written from within the OS (or even u-boot).

Thanks for the tip @tsys  =)

I am still learning embedded computing and am a u-boot novice. But I have learned the minimum required to get started. So far I have  a tiny image I have created which uses the master u-boot sources (includes your work). When burned to micro SD card, u-boot loads as expected and I am able to probe the spi flash successfully.

Looking forward to building and flashing u-boot to spi next. Have to do a little more homework first.
