Subject: [PATCH AUTOSEL 5.15 5/6] bootconfig: Increase max nodes of bootconfig from 1024 to 8192 for DCC support

From: Souradeep Chowdhury <quic_schowdhu@...cinc.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.
