[WIP] Porting EDK2 to MSM8996

How to debug?

Firstly, I need to figure out what happend if edk2 crashed from booting.

  • Using Framebuffer Serial
  • Using UART
  • Using a persistent memory

Using framebuffer output is seemly impossiable seens qualcomm is using a splash screen instead of efiframebuffer in msm8996. Which semms to be different from msm8998 and after.

Using UART is Diffcult for qualcomm device or hace qrd : Qualcomm Referenced Design

So, we are using pstore (Ramoops) for redump error and serial log.
