Hello, @gedare @opticron I have created a MR on fdt implementation for pi5 your review will be highly appreciated. Is it possible to implement bsp_fdt_copy for aarch64 based on this bootloader message
@Erick_Karanja Any update on PCIe so far? I see you have posted an MR for fdt… is it working? I have been gone for a while… I will try to get back at it most probably starting next week.
Hello @lostux I have some documentation on PCIe I will share with you. Is there any testcase related to fdt I have been searching for one.
Yes documentation would be great, thanks.
I am not sure I think the test will be if we can read the device tree nodes/properties from within the RTEMS application or not? You can look at aarch64/raspberrypi: Add FDT support (!243) · Merge requests · RTEMS / RTOS / RTEMS · GitLab and bsp/aarch64/raspberrypi: Add genet support (!313) · Merge requests · RTEMS / RTOS / RTEMS · GitLab for reference.
I noticed your MR regarding fdt support had missing build/spec changes. I added them and also added support for boot firmware fdt support using bsp_fdt_copy in a new MR. I have kept your original commit. Hope you don’t mind. 
Hello @lostux I have been caught up on some issues but I am back. I don’t mind on the MR.
