Subject: [PATCH v7 08/11] ARM: sun9i: smp: Add is_a83t field
Date: Fri, 20 Apr 2018 23:10:19 +0200	[thread overview]
Message-ID: <20180420211022.11759-9-mylene.josserand@bootlin.com> (raw)
In-Reply-To: <20180420211022.11759-1-mylene.josserand@bootlin.com>

To prepare the support of sun8i-a83t, add a field in the smp_data
structure to know if we are on sun9i-a80 or sun8i-a83t.

Add also a global variable to retrieve which architecture we are
having.
