Overview
--------
The LS1088A Reference Design (RDB) is a high-performance computing,
evaluation, and development platform that supports ARM SoC LS1088A and its
derivatives.
LS1088A SoC Overview
--------------------------------------
Please refer arch/arm/cpu/armv8/fsl-layerscape/doc/README.soc
RDB Default Switch Settings (1: ON; 0: OFF)
-------------------------------------------
For QSPI Boot
