Subject: [PATCH 6.12.y 2/2] mtd: spi-nor: macronix: add support for mx66{l2, u1}g45g
Date: Wed, 1 Jul 2026 10:42:04 +0800 [thread overview]
Message-ID: <20260701024204.2730472-2-linchengming884@gmail.com> (raw)
In-Reply-To: <20260701024204.2730472-1-linchengming884@gmail.com>
From: Cheng Ming Lin <chengminglin@mxic.com.tw>
commit 797bbaa7531f75985b199e484451fa3f954382b3 upstream.
Due to incorrect values in the 4-BAIT table for these two flash IDs,
it is necessary to add these two flash IDs with fixups.
