Subject: cxl: Move cxl_core to new directory
X-Git-Tag: accepted/tizen/unified/20230118.172025~6414^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5161a55c069f53d88da49274cbef6e3c74eadea9;p=platform%2Fkernel%2Flinux-rpi.git

cxl: Move cxl_core to new directory

CXL core is growing, and it's already arguably unmanageable. To support
future growth, move core functionality to a new directory and rename the
file to represent just bus support. Future work will remove non-bus
functionality.

Note that mem.h is renamed to cxlmem.h to avoid a namespace collision
with the global ARCH=um mem.h header.
