* Secure Boot: Implement Centaur SCOM cacheNick Bofferding2018-05-081-3/+33
| | | | | | | | | | | | | | | | | | | This change implements a Centaur SCOM cache for sensitive SCOM registers. The cache is initialized and enabled before the first Centaur SCOM, and disabled just prior to locking down the Centaur configuration. Once the Centaur has been locked down, the real register values are compared to the cache entries, and the Centaur is deconfigured (not garded) on any mismatch in assumptions.

* Work around for SCOM DMI bug on Cumulus.Donald Washburn2017-11-011-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Work-around for HW415185. On a cumulus system reads from the first 6 DMI SCOM registers need to be read twice to obtain correct values. It is desired to implement a workaround in the SCOM driver that will force a retry for any reads from these registers until a hardware fix is in place. *Implemented a framework for executing post operation actions following a scom device operation. Currently the only post operation action defined is the retry request operation. The purpose of the framework is to remove workaround logic from the device operation code and place it in easily removable individual source files as work-arounds are expected to be temporary in nature. *Move existing retry request for IBSCOM retries to a new class IbScomRetry. *Created the PostOpRetryCheck base class for the workaround framework. *Created a top-level composite pattern class used for invoking request logic - PostOpChecks. *Created a workaround class - DmiSomWorkaround for querying DMI retry requests. *Modified the doScomOp method to invoke the framework to test for retries. Removed retry recursion. *Created Unit Tests. *Created integration test.
