Subject: [PATCH v5 1/4] sparc64: implement ioremap_uc
Date: Wed, 16 Oct 2019 15:06:27 -0600 [thread overview]
Message-ID: <20191016210629.1005086-2-ztuowen@gmail.com> (raw)
In-Reply-To: <20191016210629.1005086-1-ztuowen@gmail.com>
On sparc64, the whole physical IO address space is accessible using
physically addressed loads and stores. *_uc does nothing like the
others.
