No gpio devices with enable_uboot_cape_universal=1 #57

Hi, Im struggling with getting the pin devices on my BeagleBone Black Industrial. In uEnv.txt I set _enable_uboot_capeuniversal=1 but only two devices show up. I had to load cape-universal also with _uboot_overlayaddr4=/lib/firmware/univ-bbb-xxx-00A0.dtbo. No I get a lot of pins under /sys/devices/platform/ocp. This seems not the right way to do it, but the only way I found that works. My setup:

dogtag:[BeagleBoard.org Debian Image 2018-03-05]
bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2018.01-00002-ge9ff418fb8]:[location: dd MBR]

nodejs:[v6.13.0]
uboot_overlay_options:[enable_uboot_overlays=1]

I also tried kernel 4.14 but the behavior was the same.
