prd: Implement generic HBRT - FSP interface
This patch implements generic interface to pass data from HBRT to FSP
during runtime (HBRT -> opal-prd -> kernel -> OPAL -> FSP).
HBRT sends data via firmware_request interface. We have to convert that to
MBOX format and send it to FSP. OPAL uses TCE mapped memory to send data.
FSP will reuse same memory for response. Once processing is complete FSP
sends response to OPAL. Finally OPAL calls HBRT with firmware_response
message.
Also introduces new opal_msg type (OPAL_MSG_PRD2) to pass bigger prd message
to kernel.
- if (prd_msg > OPAL_MSG_FIXED_PARAMS_SIZE)
use OPAL_MSG_PRD2
