The latest mainline U-Boot 2015.10-rc1-00597-gbbc1b99 works fine with both, sunxi 3.4 and mainline kernel.

We will switch to this version, with no default settings for LCD.

1.) On sunxi you can enable LCD with FEX.

2.) On mainline you have to recompile U-Boot with these settings:
CONFIG_VIDEO_LCD_MODE="x:1024,y:600,depth:24,pclk_khz:55000,le:100,ri:170,up:10,lo:15,hs:50,vs:10,sync:3,vmode:0"
CONFIG_VIDEO_LCD_POWER="PH12"
CONFIG_VIDEO_LCD_BL_EN="PH8"
CONFIG_VIDEO_LCD_BL_PWM="PB2"
CONFIG_VIDEO_LCD_BL_PWM_ACTIVE_LOW=n
CONFIG_VIDEO_LCD_PANEL_LVDS=y

See https://linux-sunxi.org/LCD#Bulk_automatic_conversion_of_all_FEX_files_from_the_sunxi-boards_repository [^]
