The directory structure of device tree files produced by the kernel's 'make dtbs_install' is different on ARM64, the RPi3 device tree file is in a 'broadcom' subdirectory there. Make the set_fdtfile function account for this so that the distro boot scripts can locate the DTB file.
I'm not 100% sure there's an expectation/guarantee that "make dtbs_install" will be used to create the DTB layout that the bootloader uses, although I suppose this is a reasonable thing to do.
diff --git a/board/raspberrypi/rpi/rpi.c b/board/raspberrypi/rpi/rpi.c
static void set_fdtfile(void)
- fdtfile = model->fdtfile; + if (IS_ENABLED(CONFIG_ARM64)) + strcat(fdtfile, "broadcom/"); + strcat(fdtfile, model->fdtfile);
Instead of writing code for this, and in particular code that doesn't check for buffer size/overflow/..., wouldn't it be better to simply edit the RPi 3 entry in rpi_models_new_scheme[] to contain "broadcom/" in the DTB filename string?
