Subject: [PATCH 4/9] ARM: mstar: Add infinity2m support
Date: Mon, 30 Nov 2020 22:10:42 +0900	[thread overview]
Message-ID: <20201130131047.2648960-5-daniel@0x0f.com> (raw)
In-Reply-To: <20201130131047.2648960-1-daniel@0x0f.com>

The infinity2m series of chips are like the other Mstar/Sigmastar
chips in that they have a Cortex A7 system with DDR memory integrated
in a single package.

The infinity2m chips are intended for recording the incoming streams
from IP cameras. So instead of video encoders they have video decoders,
instead of a camera interface they have display hardware and so on.

Aside from the above points the big difference about these chips is that
they include a second Cortex A7 core.
