Subject: [PATCH v2 3/4] riscv: mm: Only compile pgtable.c if MMU
Date: Wed, 13 Dec 2023 21:30:00 +0100	[thread overview]
Message-ID: <20231213203001.179237-4-alexghiti@rivosinc.com> (raw)
In-Reply-To: <20231213203001.179237-1-alexghiti@rivosinc.com>

All functions defined in there depend on MMU, so no need to compile it
for !MMU configs.
