Felix Singer 402fe20e3e mb/up/squared: Add mainboard 
Works:
- bootblock, romstage, ramstage
- Serial console UART0, UART1
- SPI flash console
- iGPU init with libgfxinit
- LAN1, LAN2
- USB2, USB3
- HDMI, DisplayPort
- eMMC
- flashing with flashrom externally

WIP:
- Documentation
- VGA
    For some reason Seabios can not find the CBFS region
    and therefore it can't load seavgabios, but generally
    it is working as soon as Linux is booted.
- ACPI

Works not:
- Devices needs proper configuration
- Seabios can't find CBFS region

Untested:
- GPIO pin header
- 60 pin EXHAT
- Camera interface
  - MIPI-CSI2 2-lane (2MP)
  - MIPI-CSI2 4-lane (8MP)
- SATA3
- USB3 OTG
- embedded DisplayPort
- M.2 slot
- mini PCIe
- flashing with flashrom internally using Linux

Board status

Working

  • bootblock, romstage, ramstage
  • Serial console UART0, UART1
  • SPI flash console
  • iGPU init with libgfxinit
  • LAN1, LAN2

Work in progress

  • Documentation
  • ACPI

Not working / Known issues

  • Generally SeaBIOS works, but it can't find the CBFS region and therefore it can't load seavgabios. This is because of changes at the Apollolake platform.

Untested

  • GPIO pin header
  • 60 pin EXHAT
  • Camera interface
