Qualcomm Glymur SoC variants predominantly boot Linux at EL2. This means
that the firmware streams of the remote processors are managed in kernel
and not in Gunyah hypervisor. Given that the Peripheral Image Loader for
Qualcomm SoCs now support running Linux Host at EL2 [1], this series
documents and enables ADSP and CDSP on Qualcomm Glymur SoCs with its
fastrpc nodes. A few variants of the SoC are expected to run Linux at EL1
hence the iommus properties are left optional.
