/// \file proc_sbe_fixed.H
/// \brief Define the layout of fixed-position data in the P9 SBE reference
/// and IPL images
///
/// Contains struct ProcSbeFixed which contains functions, rings and
/// attributes whose pointers are stored in the fixed and fixed_toc section
///
/// This file defines the layout of the special .fixed data section of P9 SBE
/// reference and IPL images. The .fixed section is guaranteed to appear at a
/// fixed offset from the beginning of the image, containing data required to
/// be manipulated when images are resident in non-volatile memories, thereby
/// avoiding having to search the TOC. Data manipulated during in-memory image
/// processing can always be easily located using the SBE-XIP TOC APIs. All
/// of the data stored in .fixed can also still be referenced via the SBE-XIP
/// TOC.
///
/// This header file can be #include-ed into either C or SBE assembly language
/// source code. In C, it creates simple structures 'ProcChipAttributes',
/// 'PervAttributes', 'CoreAttributes', 'EQAttributes' and 'EXAttributes' that
/// contain attribute information that are sized per XML definition per entry.
///
/// PPE image data is always stored big-endian, so applications on little-endian
/// hosts will need to perform the appropriate endian converison when reading or
/// writing images via this header.
///
/// In assembler code, this header creates macros '.proc_sbe_fixed_proc_chip',
/// '.proc_sbe_fixed_perv', '.proc_sbe_fixed_core', '.proc_sbe_fixed_ex',
/// '.proc_sbe_fixed_eq', that is expanded exactly once in the file
/// 'sbe_base_header.S', creating the actual data allocation of the data
/// equivalent to the C structure. Assembler code references the data symbols
/// as normal.
///
/// To simplify programming a 'mini-TOC' is also provided for this data in
/// the .fixed_toc section. This section is comprised of SbeXipHashedToc
/// structures. When a symbol is indedxed in .fixed, a blank SbeXipHashedToc
/// stucture is added to .fixed_toc. During image normalization the array of
/// SbeXipHashedToc is filled in as each symbol in .fixed is re-indexed into
/// .fixed_toc.
