LS2K1000 is a low end SoC (two core 1.0gHz), it don't has dedicated VRAM. It requires the framebuffer to be phisically continguous to scanout. The display controller in LS2K1000 don't has built-in GPIO hardware, the structure (register bit field) of its pixel, DC, GPU, DDR PLL are also defferent fr
