Subject: [PATCH 6.6.y] mtd: spi-nor: macronix: add support for mx66{l2, u1}g45g
Date: Wed,  1 Jul 2026 10:36:19 +0800	[thread overview]
Message-ID: <20260701023619.2730136-2-linchengming884@gmail.com> (raw)
In-Reply-To: <20260701023619.2730136-1-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.
