The objective is to provide a simple way to retrieve a BMP file, and display it as splashscreen, from extlinux.conf file input.

For this, we take example on https://www.syslinux.org/wiki/ index.php?title=Menu#The_advanced_menu_system and more particularly on MENU BACKGROUND chapter. For this, add "menu background" support in pxe command.

As example, extlinux.conf content will look like:

# Generic Distro Configuration file generated by OpenEmbedded menu title Select the boot mode TIMEOUT 20 menu background ../splash.bmp DEFAULT stm32mp157c-ev1-sdcard LABEL stm32mp157c-ev1-sdcard KERNEL /uImage FDT /stm32mp157c-ev1.dtb APPEND root=/dev/mmcblk0p6 rootwait rw earlyprintk console=ttySTM0,115200
