pinetab no longer shows anything on the screen after an update

22:17 < Wizzup> parazyd: looks like the pinetab image is broken for me because the boot.scr relies on u-boot to detect the hw, but my u-boot detects braveheart
22:17 < Wizzup> parazyd: hmmm but the screen also appears to be just black

I do see:

# zgrep -i feixin /proc/config.gz
CONFIG_DRM_PANEL_FEIXIN_K101_IM2BA02=y

It's possible that my pinetab is just different from all the other pinetabs, since it's just an early model (u-boot even thinks it's a braveheart pinephone)
