2020-12-28soc/mediatek/mt8192: devapc: add basic devapc driversNina Wu
Add basic devapc (device access permission control) drivers. DAPC driver is used to set up bus fabric security and data protection among hardwares. DAPC 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 DAPC driver.

2020-12-16soc/mediatek/mt8192: ufs: Disable reference clockWenbin Mei
UFS reference clock (refclk) is enabled by default, which will cause the UFSHCI to hold the SPM signal and lead to suspend failure. Since UFS kernel driver is not built-in, disable refclk in coreboot stage.

2020-10-23soc/mediatek/mt8192: Turn off L2C SRAM and reconfigure as L2 cacheCK Hu
Mediatek SoC uses part of the L2 cache as SRAM before DRAM is ready. After DRAM is ready, we should invoke disable_l2c_sram to reconfigure the L2C SRAM as L2 cache.
