The Broadcom FlexRM ring manager provides producer-consumer style ring interface for offload engines on Broadcom iProc SoCs. We can have one or more instances of Broadcom FlexRM ring manager in a SoC. This patchset adds a mailbox driver for Broadcom FlexRM ring manager which can be used by offload engine drivers as mailbox clients. The Broadcom FlexRM mailbox driver is feature complete for RAID and Crypto offload engines. We will have incremental patches in-future for ring-level statistics using debugfs and minor optimizations.
