Hi,

since we have 'file_detect_type' in barebox, we could use it to automagical=
ly
uncompress BMP files. Pseudo-code:

if (file_detect_type(bmp) !=3D BMP) {
	/* No BMP? Try to depack stream */
	ret =3D uncompress(bmp, unpacked_bmp);
	if (ret < 0 || file_detect_type(unpacked_bmp) !=3D BMP)
		return -ENOBMP;
}

Is something like this wanted? Or shall this be done entirely via scripts?

if [ $file is somehow detected as compressed ]
	uncompress $file /bmp
	bmp /bmp
	rm /bmp
else
	bmp $file
fi

?

Regards,

   Wolfram
