> Subject: [RFC PATCH 0/2] Arm build options rework
> 
> The current way of specifying Arm configuration options is insufficient since
> we can't identify the SoC we're building for from the MIDR information.
> 
> Instead use user input - the machine meson option to specify the SoC, e.g.:
> meson soc_test -Dmachine=thunderx
> meson soc_test --cross-file
> config/arm/thunderx/arm64_thunderx_linux_gcc
> 
> We also want to be able to disable which drivers (and possibly
> libraries) are built without user input. This is useful when building:
> 1. on an SoC that is slow and we want to build only what is necessary without
> the user having to check which libraries they have installed 2. a cross build on
> a fast aarch64 machine but with target SoC which differs in capabilities or
> libraries.
