ESP32-S3-LCD-EV is an ESP32-S3-based development board with a touchscreen.
Together with different subboards, ESP32-S3-LCD-EV-Board can drive LCDs with IIC,
SPI, 8080, and RGB interfaces.
It houses dual array microphones, supports voice recognition and near/far-field
voice wake-up, and features screen and voice interaction.
The board caters to development needs for touchscreen products with different resolutions
and interfaces. Currently, we have two boards available:
1. ESP32-S3-LCD-EV-Board with 480x480 LCD
2. ESP32-S3-LCD-EV-Board with 800x480 LCD

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initialization logic and the
* matching application logic. The value could be such things as a
* mode enumeration value, a set of DIP switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
