I mean the simplefb driver in the kernel in the #3, I didn't know there
is a simplefb driver in the uboot too.
So it looks like: uboot.simplefb ---> kernel.simplefb works fine
uboot.simplefb ---> kernel.simplefb ----> drm_vc4_fb works
fine (but RPI3A+ crash)
uboot.simplefb ---> kernel.simplefb ---> kernel.bcm2708_fb
makes the screen flicker
