Subject: [PATCH v3 01/10] cxl/pci: Convert register block identifiers to an enum
Date: Sat, 09 Oct 2021 09:44:02 -0700	[thread overview]
Message-ID: <163379784199.692348.4366131432595112771.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <163379783658.692348.16064992154261275220.stgit@dwillia2-desk3.amr.corp.intel.com>

From: Ben Widawsky <ben.widawsky@intel.com>

In preparation for passing around the Register Block Indicator (RBI) as
a parameter, it is desirable to convert the type to an enum so that the
interface can use a well defined parameter.
