ENGR00176235 mx6 ARD: Add splash screen support
This patch adds splash screen support for MX6 ARD.
Changes:
- Configure GPIO_3 as I2C3_SCL
- Change MAX7310 I2C address as 0x30
- Enable LVDS power
Usage:
1. To enable splash screen by default, define
CONFIG_SPLASH_SCREEN in mx6q_sabreauto.h
2. Config U-boot with followed command:()
setenv splashimage '0x30000000'
#Set splash position as Center
setenv splashpos 'm,m'
#Set LVDS via LVDS bridge 0
setenv lvds_num 0
