2024-10-28soc/mediatek/mt8196: Add PCIe driver and early init supportJianjun Wang
Add PCIe driver for MT8196 platform. According to the PCIe CEM specification, the deassertion of PERST# should occur at least 100ms after the assertion. To ensure the 100ms delay requirement is met and to save delay time in the ramstage, add an early init data region to store the elapsed time since assertion. This will speed up the boot time by 100ms. PCIe port 1 and port 2 share the same PCIe resources, but PCIe port 2 is not used. Therefore, in mtk_pcie_pre_init(), make sure PCIe port 2 is reset to prevent interference with PCIe port 1.
