Subject[RFC v2 4/7] asm/sections: add a generic push_section_tbl()
Date
With a generic linker tables solution in place we
need a general asm solution for declaring entries
with asm. The first easy target is to cover the C
asm declarations, guard the header file for now
and define a first generic entry push_section_tbl()
to be used later for custom linker table annotations.
