Subject: [PATCH v1 2/2] riscv: dts: starfive: add the missing monitor core
Date: Mon, 11 Jul 2022 19:43:26 +0100	[thread overview]
Message-ID: <20220711184325.1367393-3-mail@conchuod.ie> (raw)
In-Reply-To: <20220711184325.1367393-1-mail@conchuod.ie>

From: Conor Dooley <conor.dooley@microchip.com>

The JH7100 has a 32 bit monitor core that is missing from the device
tree. Add it (and its cpu-map entry) to more accurately reflect the
actual topology of the SoC.
