Hi all,
I'm trying to migrate the TI AM65x IOT2050 boards to OF_UPSTREAM but I'm facing issues because I need to still build the u-boot-only overlays. It is also a bit weird (but works) having to specify
CONFIG_SPL_OF_LIST="../../../../arch/arm/dts/k3-am65-iot2050-spl"
Actually, this does NOT work: I just had a long morning debugging SPL which no longer started because it picked the non-filtered dtb. The filtered one ended up in a folder outside of the u-boot sources because of all those ../ and hard-wiring to dts/upstream.
for our spl dtb.
Are there means to still build certain dtb[o] files in arch/<arch>/dts? I'm a bit lost in the Makefile forest.
Sumit: Any suggestions?
I would really like to hear some better proposals than my local workarounds to far. They don't converge although I already patched some core Makefile (overlays are building now).
OK, I side-stepped the spl issue by using one of our variant DTBs for spl as well - happens to work.
For the overlays, I need to add

ifeq ($(CONFIG_OF_UPSTREAM_BUILD_VENDOR),y)
in order to then be able to do

Does that make sense?
