It is, although the visible part doesn't change all that much.
Here are the steps with a real 16 bit image. I've also included the
tux, which gets added as the usual BMP, so if you look very carefully,
you can see that its immediate background differs a bit from the
surroundings.
SVN: developers/werner/splash
./imghs.pl >out
openocd:
halt
load_binary wherever/out 0x32000000
load_binary wherever/splashu.bmp.gz 0x32096000
resume
u-boot:
nand erase splash
nand write.e 0x32000000 splash 0x98000
setenv splashimage nand read.e 0x33d00000 splash 0x98000
setenv bootcmd bmp display 0x33d96000 185 475\; ${bootcmd}
saveenv
Note: you have to reset "bootcmd" to some reasonable default first,
i.e., one that doesn't already include "bmp ...".
