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
70 KiB large (93 KiB when built with symbols/fixup support).
Signed-off-by: Geert Uytterhoeven <geert+rene...@glider.be>
- Enlarge from 128 KiB to 1 MiB, as suggested by Peter Maydell.
