Hi Rodolfo,

Hello,
I'm planning to review the splash image support and in order to do that my next steps should be:
- Remove the logo support.
Currently we have two function for a boot screen: CONFIG_SPLASH_SCREEN and CONFIG_LCD_LOGO. I propose to remove logo support since logos must be statically compiled into u-boot and cannot be changed unless rebuild u-boot. On the other side splash images could be loaded at runtime.
- Rewrite the lcd_display_bitmap() in order to be more portable
across several BPP values.
I'd like to have some suggestions from you before starting to modify the code. :)
I already have a big rewrite of the LCD driver, as I already told you some time ago. Till now I did'nt find the time to post it, sorry. Will do so next week. It supports dynamic display configuration via FDT, which requires substantial modification.
Nevertheless, for true-color display (BPP >= 8) we should use "drivers/cfb_console.c". "common/lcd.c" just supports properly monochrome and 8-bit displays with color table. It would make more sense to spend time for a unified display driver in U-Boot. Unfortunately, that's not a trivial task.
