Subject: [PATCH AUTOSEL 5.3 118/203] soc: renesas: Enable ARM_ERRATA_754322 for affected Cortex-A9
Date: Sun, 22 Sep 2019 14:42:24 -0400 [thread overview]
Message-ID: <20190922184350.30563-118-sashal@kernel.org> (raw)
In-Reply-To: <20190922184350.30563-1-sashal@kernel.org>
From: Geert Uytterhoeven <geert+renesas@glider.be>
[ Upstream commit 2eced4607a1e6f51f928ae3e521fe02be5cb7d23 ]
ARM Erratum 754322 affects Cortex-A9 revisions r2p* and r3p*.
Automatically enable support code to mitigate the erratum when compiling
a kernel for any of the affected Renesas SoCs:
- RZ/A1: r3p0,
- R-Mobile A1: r2p4,
- R-Car M1A: r2p2-00rel0,
- R-Car H1: r3p0,
- SH-Mobile AG5: r2p2.
EMMA Mobile EV2 (r1p3) and RZ/A2 (r4p1) are not affected.
