Subject: [PATCH 6/8] cxl/Kconfig: Default drivers to CONFIG_CXL_BUS
Date: Fri, 07 May 2021 15:51:53 -0700	[thread overview]
Message-ID: <162042791307.1202325.2513845748708305095.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <162042787450.1202325.5718541949681409566.stgit@dwillia2-desk3.amr.corp.intel.com>

CONFIG_CXL_BUS is default 'n' as expected for new functionality. When
that is enabled do not make the end user hunt for all the expected
sub-options to enable. For example CONFIG_CXL_BUS without CONFIG_CXL_MEM
is an odd/expert configuration, so is CONFIG_CXL_MEM without
CONFIG_CXL_ACPI (on ACPI capable platforms). Default CONFIG_CXL_MEM and
CONFIG_CXL_ACPI to CONFIG_CXL_BUS.
