PS1, Line 1557: SCP_SSPM_DOM, DOMAIN_2
> don't we need to keep SCP/SSPM in domain2? […]

For MT8188, DEVAPC configures the hardwares(AP/others) as domain 0 by default and enables no_protection permssions for domain 0. The other domains are forbidden to access the registers.
Later, we will investigate the requirements from the module owners to configure the different domains and enable the access permissions for the different hardwares.
