additional variable "splashpos" to the environment. Please see
README for details.

allows for a "silent" boot where a splash screen is
loaded very quickly after power-on.
CONFIG_SPLASH_SCREEN_ALIGN
If this option is set the splash image can be freely positioned
on the screen. Environment variable "splashpos" specifies the
position as "x,y". If a positive number is given it is used as
number of pixel from left/top. If a negative number is given it
is used as number of pixel from right/bottom. You can also
specify 'm' for centering the image.
Example:
setenv splashpos m,m
=> image at center of screen
setenv splashpos 30,20
=> image at x = 30 and y = 20
setenv splashpos -10,m
=> vertically centered image
at x = dspWidth - bmpWidth - 9
- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
If this option is set, additionally to standard BMP
