Subject: [PATCH 4/4] powerpc/64: Define new ISA v3.00 logical PVR value and PCR register value
Date: Mon, 21 Nov 2016 16:02:35 +1100	[thread overview]
Message-ID: <20161121050235.GG26748@fergus.ozlabs.ibm.com> (raw)
In-Reply-To: <1479704214-29147-1-git-send-email-paulus@ozlabs.org>

From: Suraj Jitindar Singh <sjitindarsingh@gmail.com>

ISA 3.00 adds the logical PVR value 0x0f000005, so add a definition for
this.

Define PCR_ARCH_207 to reflect ISA 2.07 compatibility mode in the processor
compatibility register (PCR).

[paulus@ozlabs.org - moved dummy PCR_ARCH_300 value into next patch]
