../../ and make, I get these errors:

Make sure that in "Graphics support" -> "Console display driver
support", "VGA text Console" is turned OFF in make menuconfig, you only
need "Framebuffer console support" to be turned on (I stumbled
over this same error as you did before).
BTW, I got a Philips LB064V02-A1 LCD working at first try based on the info in this thread, very useful!
The LB064V02 is a 640x480 18bits color active TFT screen.
My bootargs for this Philips screen are:
setenv bootargs console=tty0 console=ttyS0,115200n8 root=1f02
I found out that this screen is quite forgiving in terms of timing, the
only settings that really make a difference between functioning and not
functioning are (for this Philips screen):
mode (if you fill in the wrong widthxheight your display will be running like a mal-adjusted old fashioned b/w tv)
outputen (polarity of the data enable line, if this one is wrongly set the lcd shows nothing)
pixclockpol (this one indicates whether it should acquire data on a
falling or rising edge of the pixclock signal. If this one is wrongly
set, the display shows nothing or shows garbage, as the data won't be
if pixclock is (very) far off, it doesn't show much on screen either.
The rest of the settings mainly concern minimal calibration and are not show stoppers if maladjusted.
TIP: if your LCD is making noise (as in a soft hissing sound) and/or
shows noise on screen, check if your ground (GND) connections are well
Now I've got another phenomena: after about 5 min. the screen goes
blank (like as if a screen saver kicked in or so), does anybody know
how to avoid this from happening?
Anyway, even if the info didn't concern an ALPS display, but I hope this helps nevertheless,
