	- Turn off L2C SRAM and reconfigure as L2 cache: 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. - Configure DMA buffer in DRAM: Set DRAM DMA to be non-cacheable to load blob correctly.

2022-07-04	soc/mediatek/mt8188: Add a stub implementation of the MT8188 SoC	Rex-BC Chen
	Add new folder and basic drivers for Mediatek SoC 'MT8188'. Difference of modules including in this patch between MT8188 and existing SoCs: Timer: Similar to MT8195 and MT8186, MT8188 uses v2 timer. EMI/PLL/SPI: Different from existing SoCs. The implementation is based on these files: MT8188G_Application Processor Technical Brief_v0.4.pdf MT8188G_Functional Specification v0.4.pdf MT8188 Application Processor Registers-1.pdf MT8188 Application Processor Registers-2.pdf TEST=saw the coreboot uart log to bootblock BUG=b:233720142 Signed-off-by: Bo-Chen Chen <rex-bc.chen@mediatek.com> Change-Id: I3320f3d49a9b9ed781ceb812e4341e379db4ac20 Reviewed-on: https://review.coreboot.org/c/coreboot/+/65585 Reviewed-by: Yu-Ping Wu <yupingso@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Yidi Lin <yidilin@chromium.org>
