/// @file p9_hcd_header_defs.H
/// @brief defines header constants based on file types
///
/// This header contains those cpp manifest constants required for processing
/// the linker scripts used to generate OCC code images. As these are used
/// by linker scripts as well as by C++ code, these cannot be solely be put
/// into a namespace. Prefixing these with the region name is the attempt
/// to make these globally unique when this header is included in C++ code.
