From: Sibi Sankar <[email protected]> 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.
