Subject: [PATCH] arm64: dts: armada-3720-espressobin: wire up spi flash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This is the storage the machine boots from by default. The partitioning
is taken from the U-Boot that is shipped with the board. There is some
more space on the flash that isn't used.
