Subject: [PATCH v4 3/3] Documentation / MTD: Rename the intel-spi driver
Date: Thu, 18 Nov 2021 16:05:43 +0300 [thread overview]
Message-ID: <20211118130543.11179-4-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20211118130543.11179-1-mika.westerberg@linux.intel.com>
Since the driver is renamed (and moved) update the BIOS upgrade guide
accordingly from intel-spi to spi-intel. Keep the guide under MTD
documentation because this is pretty much still about MTD and SPI-NOR.
