Subject: [PATCH 02/13] MIPS: cpu-probe: Mark XBurst CPU as having vtagged caches
Date: Mon, 3 Aug 2020 19:01:13 +0200 [thread overview]
Message-ID: <20200803170124.231110-3-paul@crapouillou.net> (raw)
In-Reply-To: <20200803170124.231110-1-paul@crapouillou.net>
XBurst CPUs present in Ingenic SoCs have virtually tagged caches,
according to the <cpu-features-override.h> header.
Add that information to cpu_probe_ingenic().
