Subject: [PATCH v2 4/5] arm64: dts: corstone1000: Add External System support
Date: Thu, 22 Aug 2024 18:09:50 +0100 [thread overview]
Message-ID: <20240822170951.339492-5-abdellatif.elkhlifi@arm.com> (raw)
In-Reply-To: <20240822170951.339492-1-abdellatif.elkhlifi@arm.com>
Add extsys0 remoteproc node as a child node of syscon
extsys0 describes the Corstone-1000 external system [1]
(the remote processor).
The host (Cortex-A35) can control the external system through memory mapped
registers located in a memory area called the
Host Base System Control [2][3]. This area is part of the host memory
space.
We use syscon to represent the Host Base System Control area and the
remoteproc node is a child node.
