We will need to build Image files for OpenSBI so allow that now.

OpenSBI is a much improved alternative to BBL (riscv-pk). Add OpenSBI
support to buildroot.

Hello,
I was about to apply this patch, but there is still an issue (see
below). Since a new iteration will be needed, I'll point out some minor
nits as well that I would have normally fixed myself when applying, but
that you can fix together with the more significant issue.
First minor nit: the commit title should be "boot/opensbi: new package"

So the issue that I have is that this package doesn't install anything
when OPENSBI_PLAT is empty. It doesn't install any image, it doesn't
install any library to STAGING_DIR.
Should the libplatsbi.a library be installed in
$(STAGING_DIR)/usr/lib ? This location is normally for regular Linux
user-space libraries, which I suppose libplatsbi.a is not. Perhaps it
should be in another location ?
In any case, it should be installed somewhere, otherwise the package is
pretty meaningless when OPENSBI_PLAT is empty.
Thanks!
Thomas

Use OpenSBI by default instead of riscv-pk (BBL).

If it's just the in-tree defconfig + one option to enable 32-bit
support, what about using the in-tree defconfig directly + a small
config fragment to enable 32-bit support ?
Thanks!

That would be great! That's what we do in OpenEmbedded. I couldn't
figure out how to enable that though. How can I append a config to the
arch defconfig?
