Subject: [PATCH v3 02/42] arm64: sysreg: Update ID_AA64MMFR4_EL1 description
Date: Sat, 26 Apr 2025 13:27:56 +0100	[thread overview]
Message-ID: <20250426122836.3341523-3-maz@kernel.org> (raw)
In-Reply-To: <20250426122836.3341523-1-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.
