==Customizing the splash screen==
* splashimage: RAM address where the BMP image is loaded. Please note that it must be a 32-bit aligned address with a 0x2 offset (eg: 0x20000002)
* loadsplash: comand for loading the BMP image from the storage device (e.g flash memory) to RAM. This command is automatically run by U-Boot at startup
* splashpos: image position (eg: splashpos=m,m, for centering the image)Please note that loadsplash command will differ depends on used storage device.

==== Splash image in eMMC ====
 
''TBD: replace commands with SOC's one''
 
===== U-Boot variables =====
 
<pre>

splashpos=m,m
splashsize=0x400000
</pre>
 
Please note that the eMMC first partition is used for storing the splash image file. The BMP should be present into this partition (formatted as '''ext2, ext3 or ext4''').
