From fe2c12bc0a8f9e5db87bfbf231658eadef4cdd47 Mon Sep 17 00:00:00 2001 From: Anand Moon Date: Mon, 25 Aug 2025 12:21:45 +0530 Subject: [PATCH] arm64: dts: amlogic: Add cache information to the Amlogic GXM SoCS As per the GXM datasheet add missing cache information to the Amlogic GXM SoC. - Each Cortex-A53 core has 32KB of L1 instruction cache available and 32KB of L1 data cache available. - Along with 512KB Unified L2 cache. Cache memory significantly reduces the time it takes for the CPU to access data and instructions, leading to faster program execution and overall system responsiveness.
