From 3faf2d7bb2c32a603e65f68045a58524f3018937 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 26 Apr 2018 11:04:38 +0100 Subject: [PATCH] device_tree: Increase FDT_MAX_SIZE to 1 MiB It is not uncommon for a contemporary FDT to be larger than 64 KiB, leading to failures loading the device tree from sysfs: qemu-system-aarch64: qemu_fdt_setprop: Couldn't set ...: FDT_ERR_NOSPACE Hence increase the limit to 1 MiB, like on PPC. For reference, the largest arm64 DTB created from the Linux sources is ca. 75 KiB large (100 KiB when built with symbols/fixup support).
