From cdcce47cb33a6a2ecb1bc113d0ba42ec300a33fe Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Sat, 9 Oct 2021 09:44:02 -0700 Subject: [PATCH] cxl/pci: Convert register block identifiers to an enum 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.
