An update for those testing RISC-V patches: here's a new branch of
riscv-pk/bbl that doesn't try to read or modify the DT data at all, which
should be useful until U-Boot settles down.
Here is an Linux kernel branch with updated DT data that can be booted
with the above bootloader:
A sample boot log follows, using a 'defconfig' build from that branch.
Thanks Paul, I can confirm that it works.
Something is still unclear to myself.
Using FSBL + riscv-pk/bbl the linux kernel + device tree boots.
Neither FSBL nor riscv-pk/bbl are modifying the DT.
Using FSBL + OpenSBI + U-Boot the same kernel + device tree hangs on
Would you have any pointer on what riscv-pk does that OpenSBI/U-boot doesn't ?
Or maybe it is the other way around - OpenSBI/U-boot does something that
extra that should not happen.
I don't know which version of OpenSBI you are using, but there is
a problem with the combination of kernel 5.2-rc1 and OpenSBI
versions before commit
that can result in a hang on executing init, so in case you
should be using an older OpenSBI build that might be the source
of the problem that you are experiencing.
