2022-11-04soc/mediatek/mt8188: Disable input-gating for big-core SRAMLiju-Clr Chen
The input-gating is an experimental feature (but unfortunately default enabled) and would lead to crash on MT8188, so we have to disable it in the firmware stage. BUG=b:233720142 TEST=CPUfreq in kernel test pass.

2022-08-31soc/mediatek/mt8188: Add SPM loader and initialize SPM in RAM stageRex-BC Chen
Add support for loading SPM firmware from CBFS to SPM SRAM. SPM needs its own firmware to enable SPM suspend/resume function which turns off several resources such as DRAM/mainpll/26M clk when linux system suspend. SPM is an essential component on MediaTek SoC, so we initialize PPM in soc_init(). For MT8188, SPM will handshake with DPM to do initialization, so we need to call spm_init() after dpm_init(). This SPM flow adds 33ms to the boot time. firmware log: mtk_init_mcu: Loaded (and reset) spm_firmware.bin in 25 msecs SPM: spm_init done in 33 msecs, spm pc = 0x400 TEST=spm pc is 0x400 which is in idle state.

2022-08-31soc/mediatek/mt8188: Add DEVAPC basic driverNina Wu
Add basic DEVAPC (device access permission control) driver. DEVAPC driver is used to set up bus fabric security and data protection among hardwares. DEVAPC driver groups the master hardwares into different domains and gives secure and non-secure property. The slave hardware can configure different access permissions for different domains via DEVAPC driver. 1. Initialize DEVAPC. 2. Set master domain and secure side band. 3. Set default permission. TEST=check logs of DEVAPC ok.
