tools: add tools for convert bmp to gray16 and saved as logo.img.
This tool support convert 16bpp/24bpp/32bpp bmp images into
4 bits grayscale image, and add header info to save as logo.img.
logo.img is flash into emmc and parsed in uboot to display
uboot/charging/lowpower/kernel logo.
[Note]the requirement of bmp files:
1. The resolution of all bmp image must be same.
2. The logo.img will be parsed in uboot, the uboot require the resolution
of image must be same as screen resolution, otherwise will be failed.
3. The color depth of bmp image must be 16bpp/24bpp/32bpp, 8bpp is not supported.
The usage:
./tools/bmp2gray16 --uboot-logo tools/images/eink/uboot.bmp --kernel-logo tools/images/eink/kernel.bmp
--charge-logo tools/images/eink/battery_0.bmp tools/images/eink/battery_1.bmp tools/images/eink/battery_2.bmp
tools/images/eink/battery_3.bmp tools/images/eink/battery_4.bmp tools/images/eink/battery_5.bmp
tools/images/eink/battery_fail.bmp --output ./logo.img
