Subject: [Qemu-devel] [PATCH] device_tree: Increase FDT_MAX_SIZE to 128 KiB
Date: Tue, 13 Feb 2018 17:41:17 +0100 [thread overview]
Message-ID: <1518540077-14481-1-git-send-email-geert+renesas@glider.be> (raw)
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
For reference, the largest arm64 DTB created from the Linux sources is
70 KiB large (93 KiB when built with symbols/fixup support).
