Subject: [PATCH] arm: enable RapidIO config options in Kconfig
Date: Tue, 24 Jul 2018 09:41:26 -0400	[thread overview]
Message-ID: <20180724134122.86718-1-acolin@isi.edu> (raw)

ARM SoCs with a PCI bus offer the RapiodIO config menu; SoCs with
RapidIO IP blocks but without a PCI bus, need to add "select
HAS_RAPIDIO" to the Kconfig entry for that SoC (e.g. ARCH_*).

HAS_RAPIDIO was chosen over HAVE_RAPIDIO to be consistent with
other architectures which already define this flag (powerpc).

Signed-off-by: Alexei Colin <acolin@isi.edu>
---

Tested that kernel builds with RapidIO subsystem and switch drivers enabled.
Maintainers for RapidIO subsystem CCed.
Sending a similar patch to ARM64 maintainers shortly.
