Stout base board support making use of 1 GiB of memory,
the Renesas H2 r8a7790 SoC with the SCIFA0 serial port
and CA15 with ARM architected timer.

Furthermore, this device tree contains entries for:
  - 4x LEDs
  - SDHI SD/MMC controller
  - Display unit with HDMI output
  - SH fast ethernet controller
  - QSPI controller with S25FL512S attached to it
  - I2C controller with DA9210 and DA 9063 PMICs
