Subject: [PATCH v5 09/18] powerpc/8xx: Simplify struct mmu_psize_def
Date: Mon, 10 Jun 2024 07:54:54 +0200 [thread overview]
Message-ID: <8fcfbcbc342bfa3a37a0e177f78977a0c75fbf19.1717955559.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1717955558.git.christophe.leroy@csgroup.eu>
On 8xx, only the shift field is used in struct mmu_psize_def
Remove other fields and related macros.
