2024-03-05mei: gsc_proxy: match component when GSC is on different busAlexander Usyskin1-3/+5
On Arrow Lake S systems, MEI is no longer strictly connected to bus 0, while graphics remain exclusively on bus 0. Adapt the component matching logic to accommodate this change: Original behavior: Required both MEI and graphics to be on the same bus 0. New behavior: Only enforces graphics to be on bus 0 (integrated), allowing MEI to reside on any bus. This ensures compatibility with Arrow Lake S and maintains functionality for the legacy systems.

2023-12-15mei: rework Kconfig dependenciesArnd Bergmann1-1/+1
The dependencies in the mei framework are inconsistent, with some symbols using 'select INTEL_MEI' to force it being enabled and others using 'depends on INTEL_MEI'. In general, one should not select user-visible symbols, so change all of these to normal dependencies, but change the default on INTEL_MEI to be enabled when building a kernel for an Intel CPU with ME or a generic x86 kernel. Having consistent dependencies makes the 'menuconfig' listing more readable by using proper indentation. A large if/endif block is just a simpler syntax than repeating the dependencies for each symbol.
