Hi Philipp,
2017-09-13 21:29 GMT+02:00 Philipp Tomsich philipp.tomsich@theobroma-systems.com: If a FDT was loaded (e.g. to append it to U-Boot image), we store it's address and record information for all loadables into this FDT. This allows us to easily keep track of images for multiple privilege levels (e.g. with ATF) or of firmware images preloaded into temporary locations (e.g. PMU firmware that may overlap the SPL stage).

You can see this issue with xilinx_zynqmp_zcu102_rev1_0_defconfig when you disable that option. Just a note adding dependency to Kconfig is not a proper solution because for this combination I need fit image support.
Can you please propose solution?
Thanks for the heads-up.
Sloppy editing on my part. The fdt_record_loadable function needs to be moved out of the #ifdef CONFIG_ARCH_FIXUP_FDT_MEMORY guard in common/fdt_support.c. I’ll send a patch.
Have you sent this patch?
This had fallen off my radar. The patch is on the list now.
Regards, Philipp.
