Subject: [PATCH AUTOSEL 6.2 5/6] bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support
Date: Wed, 1 Mar 2023 11:29:28 -0500 [thread overview]
Message-ID: <20230301162929.1302785-5-sashal@kernel.org> (raw)
In-Reply-To: <20230301162929.1302785-1-sashal@kernel.org>
From: Souradeep Chowdhury <quic_schowdhu@quicinc.com>
[ Upstream commit 6c40624930c58529185a257380442547580ed837 ]
The Data Capture and Compare(DCC) is a debugging tool that uses the bootconfig
for configuring the register values during boot-time. Increase the max nodes
supported by bootconfig to cater to the requirements of the Data Capture and
Compare Driver.
