The remoteproc initialization flow is similar on cores and is reuesd to avoid redundant code. The registers of config and l1tcm are shared for multi-core SCP.

The SCP driver populates the platform device and checks the child nodes to identify whether it's a single-core SCP or a multi-core SCP. The resource structure of the multi-core SCP is a list of remoteproc instances which is different to the single-core SCP. The corresponding resource releasing action is based on the type of SCP.

charset="utf-8" Because MT8195 SCP core 0 and core 1 both boot from head of SRAM and have the same viewpoint of SRAM, SCP has a "core 1 SRAM offset" configuration to control the access destination of SCP core 1 to boot core 1 from different SRAM location. The "core 1 SRAM offset" configuration is composed by a range and an offset. It works like a simple memory mapped mechanism. When SCP core 1 accesses a SRAM address located in the range, the SCP bus adds the configured offset to the address to shift the physical destination address on SCP SRAM. This shifting is transparent to the software running on SCP core 1.
