LS1046ARDB
==========
The LS1046A Reference Design Board (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1046A
LayerScape Architecture processor. The LS1046ARDB provides SW development
platform for the Freescale LS1046A processor series, with a complete
debugging environment. The LS1046A RDB is lead-free and RoHS-compliant.

Booting Options
---------------
NB: The reference manual documents the RCW source with the *least-significant
bit first*.
QSPI boot
^^^^^^^^^
This is the default. ``{ SW5[0:8], SW4[0] }`` should be ``0010_0010_0``.
SD boot and eMMC boot
^^^^^^^^^^^^^^^^^^^^^
``{ SW5[0:8], SW4[0] }`` should be ``0010_0000_0``. eMMC is selected only if
there is no SD card in the slot.
