HDMi Output on OrangePi Win/Win Plus Allwinner A64 (SUN50I)

[Anton Gorlov]

Hello.

Does u-boot support HDMI output on  OrangePi Win/Win Plus Allwinner A64 
(SUN50I) platform?
At current time HDMI output only work after linux kernel is loaded.
Before - blank screen on a monitor (no signal).

Change setting's for video-mode=sunxi.. did not give any results. Output 
only in serial console
I try:

setenv video-mode=sunxi:1024x768-24 at 60,monitor=dvi,hpd=0,edid=1
setenv video-mode=sunxi:1024x768-24 at 60,monitor=dvi,hpd=1,edid=1
setenv video-mode=sunxi:1024x768-24 at 60,monitor=dvi,hpd=0,edid=0
setenv video-mode=sunxi:1024x768-24 at 60,monitor=hdmi,hpd=0,edid=1
setenv video-mode=sunxi:1024x768-24 at 60,monitor=hdmi,hpd=1,edid=1
setenv video-mode=sunxi:1024x768-24 at 60,monitor=hdmi,hpd=0,edid=0
and
setenv hdmi.audio=EDID:0 disp.screen0_output_mode=1024x768p60
setenv hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1024x768p60


Need some help to debug this.
