It's a standard board setup with the following in the DT.
&sdhci { bus-width = <8>; mmc-hs400-1_8v; mmc-hs400-enhanced-strobe; non-removable; status = "okay"; };
&emmc_phy { status = "okay"; };
and a vanilla rk3399.dtsi from 2021.10. Do you have any idea why this might be failing?

Has anyone booted a 3399 board sucessfully since these patches went in?
Yes, chromebook_bob works OK for me.
