Subject: [PATCH v1 11/11] powerpc/microwatt: Don't select the hash MMU code
Date: Sat, 16 Oct 2021 01:46:24 +1000 [thread overview]
Message-ID: <20211015154624.922960-12-npiggin@gmail.com> (raw)
In-Reply-To: <20211015154624.922960-1-npiggin@gmail.com>
Microwatt is radix-only, so it does not require hash MMU support.
This saves 20kB compressed dtbImage and 56kB vmlinux size.
