For the moment I'll go back to my original goal of getting Pi2's to boot from the JMS-based usb-serial bridges presently on-hand. Preliminary experiments using a JMS561 bridge and a Pi2 using the version of bootcode.bin located at https://github.com/raspberrypi/firmware/raw/master/boot/bootcode.bin [referring page https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#special-bootcode-bin-only-boot-mode] seem to be promising under -current. The interest I expressed in EDK2 appears to have been misguided, or at least premature. I was hoping it might be a more tractable replacement for u-boot, but it's equally inscrutable to an amateur. Worse, only the macciatobin flavor builds under poudriere and my attempts at a plain "make" build using FLAVOR=rpi3 have so far failed on the same host. With my thanks, bob prohaska
