Rock64 USB3 booting actually works when using a microsd card for just U-Boot 2024.01, given no e.MMC present

I discovered that using a microsd card for what holds the U-Boot and not having an e.MMC at all allowed me to boot a stock aarch64 pkg base based USB3 media that I have around when plugged into the USB3 port: no custom kernels or installation of materials in odd places. U-Boot 2024.01 is what is on the microsd card. What had stopped my earlier attempts was the e.MMC speed handling issue (lack of tuning/retuning support in FreeBSD's kernel) when the e.MMC media was present. I did not have to move the microsd/E.MMC jumper from where it has been for years. This, of course, means no use of the e.MMC media that I have around, but, with USB3 and such working, I'm happy with that. No more odd procedures for booting USB3 media after all these years. What had been missing was just U-Boot being able to deal with the USB3 media for its stage (and the FreeBSD loader stage that depends on U-Boot's services). Sorry for the earlier noise where I'd guessed that FreeBSD had not tracked some Linux .dtb update. It turned out to be just the old e.MMMC speed handling issue.
