Subject: [PATCH v2 2/9] powerpc: Add Microwatt device tree
Date: Fri, 18 Jun 2021 13:44:16 +1000 [thread overview]
Message-ID: <YMwWkPcXlGDSQ9Q3@thinks.paulus.ozlabs.org> (raw)
In-Reply-To: <YMwWPcsaWzMlDPqQ@thinks.paulus.ozlabs.org>
Microwatt currently runs with MSR[HV] = 0, hence the usable-privilege
properties don't have bit 2 (for HV support) set, and we need the
/chosen/ibm,architecture-vec-5 property.
