protocol to communicate with the RPU firmware. It has
pre-defined set of messages for different message exchanges
between APU and RPU.

config CDX_BUS bool "CDX Bus driver" depends on OF && ARM64 help Driver to enable Composable DMA Transfer(CDX) Bus. CDX bus exposes Fabric devices which uses composable DMA IP to the APU. CDX bus provides a mechanism for scanning and probing of CDX devices. CDX devices are memory mapped on system bus for embedded CPUs. CDX bus uses CDX controller and firmware to scan these CDX devices.
