Subject: [PATCH V3 1/2] powerpc: Define new ISA v3.00 logical PVR value and PCR register value
Date: Tue, 1 Nov 2016 15:41:02 +1100 [thread overview]
Message-ID: <1477975263-29045-2-git-send-email-sjitindarsingh@gmail.com> (raw)
In-Reply-To: <1477975263-29045-1-git-send-email-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). Also define a dummy ISA 3.00 compatibility
mode PCR_ARCH_300 to be used in the next patch to help with determining the
PCR value.
