sysutils/opensbi: update to v0.9

[mhorne]

Summary

This change adds a patch to disable the PMP for the sifive/fu540 target,
which is a workaround to a PMP errata in the chip. The OpenSBI update
itself is quite minor.

Bump the dependent port, sysutils/u-boot-sifive-fu540.

[lwhsu]

LGTM for the port format.

@maciphone2_googlemail.com this is the same workaround I sent to you last week. Would you mind giving it another test with this version of the ports? Thanks.

I wanted this to be a compile-time check, but unfortunately could not find a clean way to rebuild this file for both opensbi targets.

Workaround looks correct.

thanks !

---edit :- --
well, compared to your Jan 21 2021-patch : https://dmesgd.nycbug.org/index.cgi?do=view&id=5888 , the OpenSBI-logo isn't displayed on boot and DRAM report differs on boot :

U-Boot 2020.10 (Feb 03 2021 - 20:49:03 +0000)

• I don't see a problem with this patch in RAM-detection :

root@:~ # sysctl hw
hw.machine: riscv
hw.ncpu: 4
hw.byteorder: 1234
hw.physmem: 8579952640

thanks again for good work !
