PS2, Line 1239: void sgx_fill_ssdt(void);
> Why is this function declaration in common code, and not somewhere in soc/intel?

ugh, that wasn't intended... should have been in `soc/intel/common/block/include/intelblocks/acpi.h`
> Why move it? intelblocks/sgx.h looks like the right place?

bc it's ACPI; other declarations are there, too
