/* 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. */

ISLAND - island ID (if it's a ME target, ME numbers are in the

CPPACTRD - CPP Read Action
