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
which depends on: CONFIG_MISC_INIT_R
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

Changes v2:
- remove keys.h - definitions should be in boards headers
- add misc.h
- code cleanup
- extend commit msg by more informations
Changes v3:
- none
Changes v4:
- code cleanup in board/samsung/common/misc.c
- add command result check
- clear PWR button interrupt flag after command finish to prevent immediately
mode exit in mode_leave_menu() function.
- introduce MODE_CMD_ARGC - max number of command arguments
- split array mode_cmd[] to mode_cmd[][] with separated arguments
- command support checking is now achieved without preprocessor ifdefs
