[PATCH] PCI: dwc: PCIE_AMD_MDB should depend on ARM64

Posted by Geert Uytterhoeven 9 months ago

The AMD MDB Versal2 PCIe controller is only present on AMD Versal2
ARM64-based SoCs.  Hence add a dependency on ARM64, to prevent asking
the user about this driver when configuring a kernel for a different
architecture than ARM64.

To be replaced by ARCH_VERSAL, if/when it ever appears for real.

Squashed into e229f853f5b277a5, thanks, Geert!
