Detection of board revision is done early - before power setup. In case of
Odroid XU3/XU4/HC1 family, the detection is done using ADC which
is supplied by LDO4/VDD_ADC regulator. This regulator could be turned
off (e.g. by kernel before reboot). If ADC is used early, the
regulators are not yet available and the detection won't work.
Split the revision detection out of set_board_type() into separate
function called later - either when displaying board info (in late mode)
or during misc_init_r. The idea is that set_board_type() will be called
early so its method of detection are limited to flattened device tree
(exynos5-dt-types.c for Exynos5) or GPIO (odroid.c for Exynos4412). The
newly added set_board_revision() can be called only later, when
resources like regulator are available.
This is necessary to fix the detection of Odroid HC1 after reboot, if
kernel turned off the LDO4 regulator.

Odroid HC2 board is based on Odroid XU4 board, like the Odroid HC1.
The linux kernel does not provide a hc2 DTB so the hc1 DTB is also used
for the Odroid HC2.

Odroid HC1 board is based on Odroid XU4 board, but it has no HDMI,
no eMMC, no build-in USB3.0 hub, no extension port pins, and no GPIO
button. USB3.0 ports are used for build-in JMicron USB to SATA bridge
and Gigabit R8152 ethernet chips. HC1 uses only passive cooling.
This patch also updates Odroid's ADCmax array and reduces ADC tolerance
to 1% to ensure that XU4 and HC1 revisions are properly detected.
I've tested this with XU3, XU3-lite, XU4 and HC1 boards. In case of my test
boards I got following values from ADC register: 372, 370, 1281 and 1313.

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

This common call can be used for setting proper entities based
on dfu command arguments.
The config: CONFIG_SET_DFU_ALT_INFO, was used only for few configs,
and now it is common.
The board file should implement:
- set_dfu_alt_info() function

This change adds declaration of functions:
- set_board_type() - called at board_early_init_f()
- get_board_type() - called at checkboard()
For supporting multiple board types in a one config - it is welcome
to display the current board model. This is what get_board_type()
should return.

This change introduces new common function:
- set_dfu_alt_info() - put dfu system and bootloader setting
into $dfu_alt_info.
functions declaration:
- char *get_dfu_alt_system(void)
- char *get_dfu_alt_boot(void)
- void set_dfu_alt_info(void)
and new config:
- CONFIG_SET_DFU_ALT_INFO
This function can be used for auto setting dfu configuration on boot.
Such feature is useful for multi board support by one u-boot binary.
Each board should define two functions:
- get_dfu_alt_system()
- get_dfu_alt_boot()

The following envs are set: soc_id, soc_rev, board_rev.
Based on this information, if CONFIG_OF_LIBFDT is enabled,
the 'fdtfile' env is set as:
fdtfile=${soc_family}${soc_id}-${board}.dtb
