Separate the probes for HSMP ACPI and platform device drivers. Provide a Kconfig option to choose between ACPI or the platform device based driver. The common code which is the core part of the HSMP driver maintained at hsmp.c is guarded by AMD_HSMP config and is selected by these two driver configs. This will be built into separate hsmp_common.ko module and acpi as hsmp_acpi and plat as amd_hsmp respectively. Also add "|| COMPILE_TEST" clause in Kconfig to get build coverage for HSMP.

Host System Management Port (HSMP) interface is a mailbox interface
|
|
between the x86 core and the System Management Unit (SMU) firmware.
|
|
The driver provides a way for user space tools to monitor and manage
|
|
system management functionality on EPYC and MI300A server CPUs
|
|
from AMD.
|
|
|
|
This option supports ACPI based probing.
|
|
You may enable this, if your platform BIOS provides an ACPI object
|
|
as described in amd_hsmp.rst document.
|
|
|
|
If you choose to compile this driver as a module the module will be
|
|
called hsmp_acpi.
