Description:

		The /sys/devices/platform/HISI0521:00/ directory contains

		some attributes about memory repair capability query and execute.



		There are following attributes in this directory:



		================= ==== =========================================

		memory_type:	       (RO) memory type the device managed.

		memory_type_supported: (RO) all memory type device the driver supports.

		acls_query:	       (WO) write with physical address to check if the

					    address support ACLS repair.

					    fails with -EINVAL if input parsing fails.

					    fails with -EIO if PCC message excution failed.

					    fails with -ENXIO if the address doesn't belong this device.

					    fails with -ENOSPC if no ACLS resource left for this address.

		acls_repair:	       (WO) write with physical address to do ACLS repair.

					    fails with -EINVAL if input parsing fails.

					    fails with -EIO if PCC message excution failed.

					    fails with -ENXIO if the address doesn't belong this device.

					    fails with -ENOSPC if no ACLS resource left for this address.

		sppr_query:	       (WO) write with physical address to check if the

					    address support sPPR repair.

					    fails with -EINVAL if input parsing fails.

					    fails with -EIO if PCC message excution failed.

					    fails with -ENXIO if the address doesn't belong this device.

					    fails with -ENOSPC if no ACLS resource left for this address.

		sppr_repair:	       (WO) write with physical address to do sPPR repair.

					    fails with -EINVAL if input parsing fails.

					    fails with -EIO if PCC message excution failed.

					    fails with -ENXIO if the address doesn't belong this device.

					    fails with -ENOSPC if no ACLS resource left for this address.
