Subject: [PATCH v4 6/6] mtd: spi-nor: manuf-id-collisions: Add support for xt25f128b
Date: Mon, 28 Feb 2022 15:45:05 +0200	[thread overview]
Message-ID: <20220228134505.203270-7-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20220228134505.203270-1-tudor.ambarus@microchip.com>

Flash does not support continuation codes and may collide with a flash
of other manufacturer, Intersil being an example. Add support for
xt25f128b.
