2016-08-12misc: add "call" uclass opStephen Warren
The call op requests that the callee pass a message to the underlying HW or device, wait for a response, and then pass back the response error code and message to the callee. It is useful for drivers that represent some kind of messaging or IPC channel to a remote device. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
