Subject: [PATCH v2 02/23] arm64: sysreg: Update ID_AA64MMFR4_EL1 description
Date: Mon, 10 Mar 2025 12:24:44 +0000 [thread overview]
Message-ID: <20250310122505.2857610-3-maz@kernel.org> (raw)
In-Reply-To: <20250310122505.2857610-1-maz@kernel.org>
Resync the ID_AA64MMFR4_EL1 with the architectue description.
This results in:
- the new PoPS field
- the new NV2P1 value for the NV_frac field
- the new RMEGDI field
- the new SRMASK field
These fields have been generated from the reference JSON file.
