While modern AARCH64 server systems use ACPI for describing the platform
topology to the OS, ARM systems and AARCH64 outside of the server space
mostly use device tree binaries, which are compiled from device tree
source files using the device tree compiler.
Currently, such source files and binaries may be kept in the EDK2 platform
trees, but are not integrated with the build, which means they need to be
kept in sync and recompiled manually, which is cumbersome.
So let's wire up BaseTools support for them: add tool definitions for the
DTC compiler and preprocessor flags that allow these source files to use
FixedPcd expressions and other macros defined by AutoGen.h
This way, a device tree binary can be built from source and emitted into
a FFS file automatically using something like:
DeviceTree.inf:
[Defines]
INF_VERSION = 0x00010019
BASE_NAME = SomePlatformDeviceTree
FILE_GUID = 25462CDA-221F-47DF-AC1D-259CFAA4E326 # gDtPlatformDefaultDtbFileGuid
MODULE_TYPE = USER_DEFINED
VERSION_STRING = 1.0
[Sources]
SomePlatform.dts
[Packages]
MdePkg/MdePkg.dec
SomePlatform.fdf:
INF RuleOverride = DTB xxx/yyy/DeviceTree.inf
[Rule.Common.USER_DEFINED.DTB]
FILE FREEFORM = $(NAMED_GUID) {
RAW BIN |.dtb
}
where it can be picked at runtime by the DTB loader that may refer to it
using gDtPlatformDefaultDtbFileGuid.
Note that this is very similar to how ACPI tables may be emitted into a
FFS file with a known GUID and picked up by AcpiTableDxe at runtime.

Any time I have to review a tools_def.template / build_rule.template
patch, I'm in trouble :)

Do we care about "?.DTS" files as well? Some other rules spell out both
lower and upper case.

Is there a strong reason to make this GCC toolchain family specific?
The example I'm looking at is NASM. Is it possible that someone wants to
(cross-build) for ARM without a GCC toolchain? (Of course we can add
that later then.)

Seems to match other rules, yes.

Seems good.

Call this UNIX_DTC_BIN, for future-proofing? (Could be a terrible
comment, sorry about that.)
Also, I have zero clue if this is the right location in the file to
define this macro.

OK, this makes sense. I tried to see if another (preexistent) define
would be reusable, but nothing seems to.

I asked some idea-questions to hide how confused I generally am about
these two files.

The reason is a practical one: while ARM is supported by RVCT as well,
nobody actually uses that, and so GCC is the only toolchain I bothered
to add. If anyone wants to contribute other toolchain support (and is
able to test it), that's fine with me.

Not sure why you would want to configured a single environment for
both Windows and Unix, so having UNIX and WINDOWS flavors seems rather
pointless to me.

Nope, not really. dtc barfs on any C style constructs, but we can't
use Trim, so using this with -imacros is the most appropriate.

>
>While modern AARCH64 server systems use ACPI for describing the platform
>topology to the OS, ARM systems and AARCH64 outside of the server space
>mostly use device tree binaries, which are compiled from device tree
>source files using the device tree compiler.

>FixedPcd expressions and other macros defined by AutoGen.h
