Subject: [PATCH v6 14/23] powerpc/8xx: Simplify struct mmu_psize_def
Date: Mon, 24 Jun 2024 16:45:40 +0200	[thread overview]
Message-ID: <c5ad47f72091771e2ae483ee6b52b74b1a5fc172.1719240269.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1719240269.git.christophe.leroy@csgroup.eu>

On 8xx, only the shift field is used in struct mmu_psize_def

Remove other fields and related macros.
