Subject: RiscV SBI incompatibilities?

Hi folks,
maybe I tried something stupid, but it felt like a good idea at first.
I am updating my VisionFive 2 board from an oldish installation with
U-Boot 2024.10.
To have as few moving parts as possible, I build 2026.10 with the same SBI
that I had lying around from the original 2024.10 build, which happend
to be OpenSBI 1.4.
This failed spectacularily: most sbc_* calls for HSM fail with
-3 (SBI_ERR_INVALID_PARAM).
A few calls worked, like sbi_hart_start() and sbi_hart_get_status(),
which told me the hartids I was using were valid, but then doing
e.g. sbi_send_ipi() or sbi_remote_sfence_vma() failed.
Does this ring a bell? Is it expected? Did I overlook a "minimal SBI version
1.X" somewhere?
Martin
