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
