Does this ARI firmware sit in the Arm cores' DRAM? If so, can you share which memory region it needs? Same question for BL31 - is that TZDRAM_BASE? If so, where to find the size? The TF-A docs are not so telling of those layout details. https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/nvidia-tegra.rst U-Boot only reserves any memrsv entries of the FDT, not other memory nodes such as within your sysram@30000000. Those may need C code in U-Boot to reserve them from usage by UEFI apps such as GRUB and Linux. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/arch/arm64/boot/dts/nvidia/tegra186.dtsi Regards, Andreas -- SUSE Linux GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Mary Higgins, Sri Rasiah HRB 21284 (AG Nürnberg) _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
