[Embeded Linux] L3.0.35_4.1.0_uboot_logo_keep_patch_2013-11-22 DL : 0: iMX6平台u-boot启动后会运行液晶初始化程序并显示启动LOGO，但进入linux系统之后，又重新初始化一次，而且uboot与linux定义的显存地址也不一致，导致会有短暂的白屏闪烁。此补丁解决从uboot到linux启动完成一直保持LOGO不变，且中间不闪烁不闪屏。(U-boot runs the LCD initializer and displays the LOGO boot, but after entering the Linux system, it is reinitialized again, and the memory address defined by u boot and Linux is not the same, resulting in a brief white screen flicker. This patch solves the problem of keeping LOGO unchanged from uboot to Linux, and does not flicker in the middle.)
