Help text

Enable the CXL core to enumerate and provision CXL regions. A CXL region is defined by one or more CXL expanders that decode a given system-physical address range. For CXL regions established by platform-firmware this option enables memory error handling to identify the devices participating in a given interleaved memory range. Otherwise, platform-firmware managed CXL is enabled by being placed in the system address map and does not need a driver.
