> Subject: [PATCH v17 1/3] build: disable/enable drivers in Arm builds
> 
> Add support for enabling or disabling drivers for Arm cross build. Do not
> implement any enable/disable lists yet.
> 
> Enabling drivers is useful when building for an SoC where we only want to
> build a few drivers. That way the list won't be too long.
> 
> Similarly, disabling drivers is useful when we want to disable only a few
> drivers.
> 
> Both of these are advantageous mainly in aarch64 -> aarch64 (or arch -> same
> arch) builds, where the build machine may have the required driver
> dependencies, yet we don't want to build drivers for a specific SoC.
> 
> By default, build all drivers for which dependencies are found. If
> enabled_drivers is a non-empty list, build only those drivers.  If
> disabled_drivers is non-empty list, build all drivers except those in
> disabled_drivers. Error out if both are specified (i.e. do not support that case).
> 
> There are two drivers, bus/pci and bus/vdev, which break the build if not
> enabled. Address this by always enabling these if the user disables them or
> doesn't specify in their allowlist.
> 
> Also remove the old Makefile arm configuration options which don't do
> anything in Meson.
