This series refactors SSDT runtime composing and gets rid of:
* patching AML templates, with related pointer arithmetic magic
* manual AML composition, i.e. creating AML terms practically
byte by byte
* using AML templates for SSDT creation, reducing dependency on IASL.
as result of above, QEMU source tree doesn't have to carry
'binary' template blobs that used to be part of SSDT.
* hand-crafted PCI0._CRSes for pc/q35 machines in DSDT with
manual hole punching of reserved resources
and adds following:
* introduces ASL like API for creating AML objects using ASL
like constructs/terms. API:
* provides a necessary minimum set of terms/helpers to
replace currently used SSDT templates.
* simplifies AML composition and keeps track of AML
object contexts, transparently managing their
(de)allocation and merging into parent context,
making composition of SSDT 'almost' like writing
native ASL definition of the table.
* hides pointer arithmetic from user when composing
SSDT.
* dynamically creates unified PCI0._CRS in SSDT for pc/q35
machines allowing to reserve resources at runtime vs
current compile time
* while adding new API, make it target independed CONFIG_ACPI
and also make some other utilities for composing ACPI tables
target independed (i.e. utils on which API depends) so that
they could be reused for ARM target later without moving
stuff around uncessarily.
As result of replacing AML templates with ASL API, codebase
reduces on ~1800LOC even with net addition of API 1050LOC counted in.
Tested with XPsp3, WS2012R2, RHEL6/7 guests.
