plat/arm: Introduce corstone700 platform. This patch adds support for Corstone-700 foundation IP, which integrates both Cortex-M0+ and Cortex-A(Host) processors in one handy, flexible subsystem. This is an example implementation of Corstone-700 IP host firmware. Cortex-M0+ will take care of boot stages 1 and 2(BL1/BL2) as well as bringing Host out RESET. Host will start execution directly from BL32 and then will jump to Linux. It is an initial port and additional features are expected to be added later.

Corstone700: add support for mhuv2 in arm TF-A Note: This patch implements in-band messaging protocol only. ARM has launched a next version of MHU i.e. MHUv2 with its latest subsystems. The main change is that the MHUv2 is now a distributed IP with different peripheral views (registers) for the sender and receiver. Another main difference is that MHUv1 duplex channels are now split into simplex/half duplex in MHUv2. MHUv2 has a configurable number of communication channels. There is a capability register (MSG_NO_CAP) to find out how many channels are available in a system. The register offsets have also changed for STAT, SET & CLEAR registers from 0x0, 0x8 & 0x10 in MHUv1 to 0x0, 0xC & 0x8 in MHUv2 respectively. 0x0 0x4 0x8 0xC 0x1F ------------------------....----- | STAT | | | SET | | | ------------------------....----- Transmit Channel 0x0 0x4 0x8 0xC 0x1F ------------------------....----- | STAT | | CLR | | | | ------------------------....----- Receive Channel The MHU controller can request the receiver to wake-up and once the request is removed, the receiver may go back to sleep, but the MHU itself does not actively put a receiver to sleep. So, in order to wake-up the receiver when the sender wants to send data, the sender has to set ACCESS_REQUEST register first in order to wake-up receiver, state of which can be detected using ACCESS_READY register. ACCESS_REQUEST has an offset of 0xF88 & ACCESS_READY has an offset of 0xF8C and are accessible only on any sender channel. This patch adds necessary changes in a new file required to support the latest MHUv2 controller. This patch also needs an update in DT binding for ARM MHUv2 as we need a second register base (tx base) which would be used as the send channel base.
