Subject: [PATCH v2 16/16] powerpc/microwatt: Don't select the hash MMU code
Date: Thu, 21 Oct 2021 13:54:17 +1000 [thread overview]
Message-ID: <20211021035417.2157804-17-npiggin@gmail.com> (raw)
In-Reply-To: <20211021035417.2157804-1-npiggin@gmail.com>
Microwatt is radix-only, so it does not require hash MMU support.
This saves 20kB compressed dtbImage and 56kB vmlinux size.
