Subject: [PATCH v2 12/14] hw/arm/mps2: Add I2C devices
Date: Wed, 17 Jun 2020 07:52:03 +0200 [thread overview]
Message-ID: <20200617055205.3576-13-f4bug@amsat.org> (raw)
In-Reply-To: <20200617055205.3576-1-f4bug@amsat.org>
From 'Application Note AN385', chapter 3.14:
The SMM implements a simple SBCon interface based on I2C.
There are 4 SBCon interfaces on the FPGA APB subsystem.
