      exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4. · 1611c8cb
      Przemyslaw Marczak authored
      This commit adds additional file with implementation of board
      detection code for Odroid-XU3/XU4.
      
      The detection depends on compatible found in fdt:
      - "samsung,exynos5" - uses Exynos5 generic code
      - "samsung,odroidxu3" - try detect XU3 revision
      
      There are few revisions of Odroid XU3/XU4, each can be detected
      by checking the value of channel 9 of built-in ADC:
       Rev   ADC  Board
       0.1     0  XU3 0.1
       0.2   372  XU3 0.2 | XU3L - no DISPLAYPORT
       0.3  1280  XU4 0.1
      
      The detection code depends on the ADC+10% value.
      
      Implementation of functions:
      - set_board_type()     - read ADC and set type
      - get_board_rev()      - returns board revision: 1..3
      - get_board_type()     - returns board type string
      
      Additional functions with return values of bool:
      - board_is_generic()   - true if found compatible "samsung,exynos5"
                               but not "samsung,odroidxu3"
      - board_is_odroidxu3() - true if found compatible "samsung,odroidxu3"
                               and one of XU3 revision.
      - board_is_odroidxu4() - true if found compatible "samsung,odroidxu3"
                               and XU4 revision.
      
      After I2C controller init, the get_board_type() can check
      if the XU3 board is a "Lite" variant, by probing chip
      0x40 on I2C0 (INA231 - exists only on non-lite).
      This is useful for setting fdt file name at misc_init_r().
      
      Enabled configs:
      - CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
      - CONFIG_ODROID_REV_AIN
      - CONFIG_REVISION_TAG
      - CONFIG_BOARD_TYPES
