exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.

2015-11-02T01:38:00+00:00

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

dfu: samsung: move call to set_dfu_alt_info() to dfu common code

2015-02-25T16:47:02+00:00

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

samsung: board: enable support of multiple board types

2014-09-05T04:58:50+00:00

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.

samsung: misc: add function for setting $dfu_alt_info

2014-09-05T04:58:49+00:00

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()

board:samsung:common: set envs with board unified information

2014-02-07T01:06:24+00:00

This patch sets envs that describe board information.
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

The generated envs are intenionally not saved to persistent storage.

This simple LCD menu allows run one of download mode on device
without writing on console or for fast and easy upgrade.

This feature check user keys combination at boot:
- power key + volume up - download menu
- power key + volume down - thor mode (without menu)

New configs:
- CONFIG_LCD_MENU
- CONFIG_LCD_MENU_BOARD

For proper effect this feature needs following definitions:

Power key:
- KEY_PWR_PMIC_NAME - (string) pmic which supports power key check

Register address:
- KEY_PWR_STATUS_REG
- KEY_PWR_INTERRUPT_REG

Register power key mask:
- KEY_PWR_STATUS_MASK
- KEY_PWR_INTERRUPT_MASK

Gpio numbers:
- KEY_PWR_INTERRUPT_MASK
- KEY_VOL_DOWN_GPIO

Functions needs to be called:
- keys_init() - for set proper gpio direction
- check_boot_mode() - menu - main function
