There are three primary modifications.
1. The struct mtk_scp_of_data usage on MT8188
MT8192 functions are unsuitable for the dual-core MT8188 SCP,

We've added MT8188-specific functions to configure L1TCM
in

Under different applications, the MT8188 SCP can be used as single-core
or dual-core.

Hi
I wonder if there is a way to attach a probe to a timeout in process

This spun off from https://social.kernel.org/notice/Ah18GN3aezWLdcxcAK
