[PATCH v2 16/16] powerpc/microwatt: Don't select the hash MMU code
From: Nicholas Piggin <npiggin@gmail.com>
Date: 2021-10-21 04:05:10
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
Microwatt is radix-only, so it does not require hash MMU support. This saves 20kB compressed dtbImage and 56kB vmlinux size.
