Add opal calls to interact with the NPU: OPAL_NPU_SPA_SETUP: set the Shared Process Area (SPA) The SPA is a table containing one entry (Process Element) per memory context which can be accessed by the opencapi device. OPAL_NPU_SPA_CLEAR_CACHE: clear the context cache The NPU keeps a cache of recently accessed memory contexts. When a Process Element is removed from the SPA, the cache for the link must be cleared. OPAL_NPU_TL_SET: configure the Transaction Layer The Transaction Layer specification defines several templates for messages to be exchanged on the link. During link setup, the host and device must negotiate what templates are supported on both sides and at what rates those messages can be sent.
