Subject: [PATCH linux dev-5.15 23/26] mtd: spi-nor: spansion: s25fl256s0: Skip SFDP parsing
Date: Fri, 25 Feb 2022 10:42:18 +0800	[thread overview]
Message-ID: <20220225024221.19422-24-potin.lai@quantatw.com> (raw)
In-Reply-To: <20220225024221.19422-1-potin.lai@quantatw.com>

From: Tudor Ambarus <tudor.ambarus@microchip.com>

s25fl256s0 does not define the SFDP tables nor implements the
RDSFDP 0x5a command. Skip the SFDP parsing in order to avoid
issuing an unsupported command to the flash.
