+ * GetVersion, GetCapabilities, GetStatus, GetInfo, ResolveAddress,
+ * GetNextBlock, and GetBlock. This means that control returns to the caller
+ * with a relevant status code only after the completion of the operation (or
+ * the discovery of a failure condition).
+ *
+ * The remainder of the APIs: Initialize, Uninitialize, PowerControl, ReadData,
+ * ProgramData, Erase, EraseAll, can function asynchronously if the underlying
+ * controller supports it--i.e. if ARM_STORAGE_CAPABILITIES::asynchronous_ops is
+ * set. In the case of asynchronous operation, the invocation returns early
+ * (with ARM_DRIVER_OK) and results in a completion callback later. If
+ * ARM_STORAGE_CAPABILITIES::asynchronous_ops is not set, then all such APIs
+ * execute synchronously, and control returns to the caller with a status code
+ * only after the completion of the operation (or the discovery of a failure
+ * condition).
+ *
+ * If ARM_STORAGE_CAPABILITIES::asynchronous_ops is set, a storage driver may
+ * still choose to execute asynchronous operations in a synchronous manner. If
+ * so, the driver returns a positive value to indicate successful synchronous
+ * completion (or an error code in case of failure) and no further invocation of
+ * completion callback should be expected. The expected return value for
+ * synchronous completion of such asynchronous operations varies depending on
+ * the operation. For operations involving data access, it often equals the
+ * amount of data transferred or affected. For non data-transfer operations,
+ * such as EraseAll or Initialize, it is usually 1.
+ *
+ * Here's a code snippet to suggest how asynchronous APIs might be used by
+ * callers to handle both synchronous and asynchronous execution by the
+ * underlying storage driver:
+ * \code
+ * ASSERT(ARM_DRIVER_OK == 0); // this is a precondition; it doesn't need to be put in code
+ * int32_t returnValue = drv->asynchronousAPI(...);
+ * if (returnValue < ARM_DRIVER_OK) {
+ * // handle error.
+ * } else if (returnValue == ARM_DRIVER_OK) {
+ * ASSERT(drv->GetCapabilities().asynchronous_ops == 1);
+ * // handle early return from asynchronous execution; remainder of the work is done in the callback handler.
+ * } else {
