Starting from MT8196, MediaTek platform introudces a new blob named
MediaTek firmware support package (mtk-fsp). The features of mtk-fsp
include but not limit to,
- Security settings, e.g: Device Access Proctection Control, Security
Memory Protection Unit.
- Initialization for advanced CPU frequency control.
This patch implements APIs for
1) Exchanging data between coreboot and mtk-fsp.
2) Loading and running the mtk-fsp blob at a specific bootstage.

Mediatek SoCs start operating at eMMC clock around 3MHz right after
power-on due to wrong src_hz value. In JEDEC spec, eMMC clock needs
under 400kHz.
When we need to set a clock output frequency, we actually set a
frequency division value. Originally, we set the source clock
frequency to 50MHz, the target frequency to 400KHz, and get the
division value 128. However, the actual source clock frequency is
400MHz, so the final actual output is 400MHz/128=3.125MHz.
So we correct source clock frequency to 400MHz for eMMC output
clock of 400KHz.
