So I take it I could use my version of U-boot to load BBL,
then your S-mode U-boot?
I've been holding off on refactoring or submitting anything
from the MicroSemi U-boot that runs in M-mode and inits the
DRAM until I have some decent method to regression test the
whole system (bootloader, kernel, userspace). I also want
to make sure we don't break any other RiscV platforms when
we add new code.
It looks HiFive unleashed boards are available for purchase
again, is there any place to get an AndesTech board?
(fyi, the *proof of concept* hacks for regression testing
that work for me based on MicroSemi patches are at
https://github.com/tmagik/freedom-u-sdk/tree/regression/kernel4.15 )
