Subject: [PATCH 3/8] arm: remove TTB_SECT_XN_MASK in DCACHE_WRITETHROUGH
Date: Fri, 5 Feb 2021 13:53:34 +0100	[thread overview]
Message-ID: <20210205135332.3.Ic60984b860abed150b9bead538770cd1b6d930fe@changeid> (raw)
In-Reply-To: <20210205125339.24721-1-patrick.delaunay@foss.st.com>

The normal memory (other that DCACHE_OFF) should be executable by default,
only the device memory (DCACHE_OFF) used for peripheral access should have
the bit execute never (TTB_SECT_XN_MASK).
