Subject: [PATCH 1/6] arch-armv8a.inc: add tune include for armv8
Date: Mon, 4 Feb 2019 18:57:22 -0800 [thread overview]
Message-ID: <20190205025727.1937-1-raj.khem@gmail.com> (raw)
From: ayaka <ayaka@soulik.info>
There are some addtional instructions apart from bare armv8,
also there is armv8.1, armv8.2.
Most the processor would support crc, except X-gene 1.
