Needless to say if I let it try to continue it fails as it can't find 
the SD card and "mmc dev" shows nothing present.

Obviously going to dig into this further myself but I recalled something 
about this uBoot version being broken on older Pis...

I would not be the first time that a u-boot update break booting on a
board. I didn't test on RPI* the last two (or three) update.
Just to be sure could you test the official image ? Latest armv7
14-CURRENT snapshot should have the last u-boot.

Karl reported that he was using boot1.efi instead of
loader.efi and just substituting in the likes of
loader.efi got booting to work.

Why boot1.efi ? Because that is what Crochet put in
place.

Yes, and I remember when 13-x first showed up on my AMD box suddenly boot1 blew up there too which was a nasty little and unexpected surprise.  Not a big deal to fix once you realize what is going on but given the fact that u-boot updates have blown up booting on these devices before (and I've kept older versions around for this reason) that prompted me to ask if anyone else had seen a similar problem with the older Pi2s (my '3s are all ok with modern builds) on 13.x

I've fixed Crochet to build and use the lua loader rather than boot1 for EFI and it appears to be working fine.
