/* NFP SECTION flags
ELF-64 sh_flags is 64-bit, but there is no info on what the upper 32 bits
are expected to be used for, it is not marked reserved either.
We'll use them for NFP-specific flags since we don't use ELF-32.
INIT - Sections that are loaded and executed before the final text
microcode. Non-code INIT sections are loaded first, then other
memory secions, then INIT2 sections, then INIT-code sections.
INIT2 - Sections that are loaded before INIT-code sections, used for
transient configuration before executing INIT-code section
microcode.
SCS - The number of additional ME codestores being shared with the group's
base ME of the section, e.g. 0 for no SCS, 1 for dual and 3 for
quad. If this is 0 it is possible that stagger-style SCS codestore
sections are being used. For stagger-style each section is simply
loaded directly to the ME it is assigned to. If these flags are
used, virtual address space loading will be used - one large section
loaded to the group's base ME will be packed across shared MEs by
hardware. This is not available on all ME versions.
NFP_ELF_SHF_GET_SCS (val) returns the number of additional codestores
being shared with the group's base ME, e.g. 0 for no SCS,
1 for dual SCS, 3 for quad SCS. */
