Can we move as many as possible from these files under a separate
subdirectory? For example, "PlatformBuild.py" seems to be referenced
explicitly by the other files, so I guess at least "PlatformBuild.py"
could be "tucked away".
My intent with this request is two-fold:
- collect CI-related files ("metafiles") in their own dedicated space,
- when someone runs "ls -l" in the package root dir, prevent them from
thinking that e.g. "PlatformBuild.py" or "iasl_ext_dep.yaml" are somehow
necessary (or useful) for building locally.
Otherwise I'm ready to ACK this patch!
Thanks,
Laszlo

> +1. Including the expected build architecture and toolchain to the
> _stuart_update_ command is critical. This is because there are extra scopes
> and tools that will be resolved during the update step that need to match
> your build step.
> +2. Configuring _ACTIVE_PLATFORM_ and _TARGET_ARCH_ in Conf/target.txt is
> _not_ required. This environment is set by PlatformBuild.py based upon the
> "`[-a <TARGET_ARCH>]`" parameter.
> +3. QEMU must be on your path. On Windows this is a manual process and not
> part of the QEMU installer.
> +
> +**NOTE:** Logging the execution output will be in the normal stuart log as
> well as to your console.

> +## Custom Build Options
> +
> +**MAKE_STARTUP_NSH=TRUE** will output a _startup.nsh_ file to the location
> mapped as fs0. This is used in CI in combination with the --FlashOnly feature
> to run QEMU to the UEFI shell and then execute the contents of startup.nsh.
> +
> +**QEMU_HEADLESS=TRUE** Since CI servers run headless QEMU must be told to
> run with no display otherwise an error occurs. Locally you don't need to set
> this.
> +
> +## Passing Build Defines
> +
> +To pass build defines through _stuart_build_, prepend `BLD_*_`to the define
> name and pass it on the command-line. _stuart_build_ currently requires
> values to be assigned, so add an`=1` suffix for bare defines.
> +For example, to enable the TPM2 support, instead of the traditional "-D
> TPM2_ENABLE=TRUE", the stuart_build command-line would be:
> +
> +`stuart_build -c ArmVirtPkg/PlatformBuild.py BLD_*_TPM2_ENABLE=TRUE`
