Subject: [PATCHv1 5/5] arm64: dts: amlogic: Add cache information to the Amlogic A7 SoC
Date: Mon,  5 Feb 2024 22:49:23 +0530	[thread overview]
Message-ID: <20240205171930.968-6-linux.amoon@gmail.com> (raw)
In-Reply-To: <20240205171930.968-1-linux.amoon@gmail.com>

As per A311D datasheet add missing cache information to the Amlogic A7 SoC.

- Each Cortex-A53 core has 32 KB of instruction cache and
	32 KB of L1 data cache available.
- Each Cortex-A73 core has 64 KB of L1 instruction cache and
	64 KB of L1 data cache available.
- The little (A53) cluster has 512 KB of unified L2 cache available.
- The big (A73) cluster has 1 MB of unified L2 cache available.

To improve system performance.
