VisionFive 2 Boot/Root Device

[gary%duzan.org@localhost]

   I have a VisionFive 2 board that I bought to play with. It boots the
StarFive Debian image fine, but it doesn't do as well with a NetBSD
riscv64.img image downloaded recently from releng. Once I sorted out
the serial console, I got the boot log which I have uploaded here:

The boot/root should be the microSD card, but while I see dwcmmc[01], I
don't see sdmmc? or ld?. I am new to the hardware platform, so I could be
missing something obvious.

   Let me know if there is anything I can do to help. I don't need to run
NetBSD on this board, but I would prefer it.
