The RISC-V Platform Management Interface (RPMI) defines a messaging protocol and shared memory based transport for bi-directional communication with an on-chip or external microcontroller. To support RPMI in OpenSBI, add: 1) The RPMI messaging protocol defines and helper macros 2) A FDT mailbox driver for the RPMI shared memory transport Signed-off-by: Rahul Pathak <rpathak@ventanamicro.com> Co-developed-by: Subrahmanya Lingappa <slingappa@ventanamicro.com> Signed-off-by: Subrahmanya Lingappa <slingappa@ventanamicro.com> Co-developed-by: Anup Patel <apatel@ventanamicro.com> Signed-off-by: Anup Patel <apatel@ventanamicro.com>
