If I manage to convince mst in using macro approach.
PS:
Although his build_append_foo() functions have tremendously improved
dynamic AML generation (made it much less error-prone), the
current acpi-build.c becomes harder to read (just look at new pcihp
parts). So I'm arguing in favor of more simple/intuitive API
approach even if it uses macros (I'm really not fun of it,
but result is much clear/maintainable code).
