This patch set is to emulate translate SPA feature by nfit_test.ko.
Certainly the nfit acpi driver supports translate SPA interface
via ND_CMD_CALL. But nfit_test does not support it yet.
To test translate SPA with nfit_test, this patch set is needed.
Change log since v1 :
- Separate patch set of kenel from ndctl patch set.
- Change interface via ND_CMD_CALL.
