Subject: [PATCH 02/17] MIPS: Modify the Loongson1 PRID_REV
Date: Sat, 29 Jul 2023 21:43:03 +0800	[thread overview]
Message-ID: <20230729134318.1694467-3-keguang.zhang@gmail.com> (raw)
In-Reply-To: <20230729134318.1694467-1-keguang.zhang@gmail.com>

Because LS1B and LS1C share the same PRID,
it's reasonable to rename their PRID_REVs to PRID_REV_LOONGSON1.
