From 5aa39a9165cfc80d37f1db8ba8fee798a3ecf74f Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 14 Jun 2023 18:30:13 -0700 Subject: cxl/port: Rename CXL_DECODER_{EXPANDER, ACCELERATOR} => {HOSTONLYMEM, DEVMEM} In preparation for support for HDM-D and HDM-DB configuration (device-memory, and device-memory with back-invalidate). Rename the current type designators to use HOSTONLYMEM and DEVMEM as a suffix. HDM-DB can be supported by devices that are not accelerators, so DEVMEM is a more generic term for that case. Fixup one location where this type value was open coded.
