I think it would be nice to keep Fastboot as a fallback, e.g. when a
button is pressed during boot. Some people may want that for updating
U-Boot itself.

I had this mapped to the Volume Down button in my original change:
https://github.com/stericsson-mainline/u-boot/commit/3a499aabe598004da889c507095edf8d9b21244e

Nowdays it's a bit easier to do this without extra C code using
button_cmd, see e.g.
https://git.u-boot-project.org/u-boot/u-boot/-/commit/359e1d4a57e06ab662ca7e008e881da27e9d3562

Thanks,
