Subject: [PATCH 3/3] arch: arm: imx: spi: Add QSPI boot option to the IMX8MN-EVK
Date: Tue,  8 Mar 2022 17:08:01 +0100	[thread overview]
Message-ID: <20220308160801.782206-4-joacim.zetterling@westermo.com> (raw)
In-Reply-To: <20220308160801.782206-1-joacim.zetterling@westermo.com>

Add lowlevel board functionality to be able to boot from
a QSPI device.

Also added configuration parameters for a QSPI device to be
included in a final QSPI boot image.
All configuration for a QSPI boot image are controlled within
the board flash header configuration file.
