SceDisplay

This module handles management of the framebuffers. It uses various display drivers (OLED, HDMI, LCD) as well as drivers to control DMA and other low level details. Embedded in this module is also the boot logo (the PS logo seen on boot) which is gzipped. On module_start, after setting up the drivers, it gunzips the logo into the SceCamera SRAM (which is unused at this time since camera is not enabled yet). Then it sets the framebuffer to the camera SRAM and turns the brightness up in incremental levels.
