-               specified in "splashimage" is loaded instead. The

-
-               If this option is set, then U-Boot will prevent the environment

-               (see doc/README.displaying-bmps).

-               restrictions, an improperly aligned BMP image will cause a data
-               abort. If you think you will not have problems with unaligned
-               accesses (for example because your toolchain prevents them)
-               there is no need to set this option.

-
-               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

-               setenv splashpos 30,20
