+The u-boot setup is specific to a quartus design. Generate handoff files from +the design. Pass them to a python script to produce a handoff.h file. This is +needed as input for building the device-tree for u-boot. Eventually, building +the final u-boot depends on the particular Quartus design, the particular +carrier board, the selected boot media and boot mode.
+Enclustra provides reference design examples which can be built with yocto +using their meta-layer.

+Quick Start +-----------
+- Setup and build a Quartus design project +- Obtain the hps.xml file from the Quartus design project +- Generate the handoff.h file for u-boot +- Adjust the device-tree file according to your setup +- Build u-boot +- Flash u-boot
+Build U-Boot +------------
+The Quartus design produces a design specific ``hps.xml``, an ``emif.xml`` and +a corresponding ``id`` file contained in a folder ``handoff``.

Have a look at 'sfdisk' tool, scriptable fdisk , that is preferable .

+Boot Media +----------
+Alternative boot media are possible as officially documented by Enclustra.

+NB: eMMC and QSPI can be flashed from off the u-boot shell. Usually after
What does 'NB:' stand for ?
+flashing, the coorect boot mode needs to be set by a BSEL switch. Approaches +are described consistently in the offical Enclustra documentation according to
"official", typo, run the docs through e.g. aspell to catch those typos.
