From 5e0c7044b9149fb39f13494d4baaedbe7ae7bed9 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 7 Nov 2017 13:03:51 +0000 Subject: hw/arm: Mark the "fsl,imx25" device with user_creatable = false QEMU currently crashes when the user tries to instantiate the fsl,imx25 device manually: $ aarch64-softmmu/qemu-system-aarch64 -S -M imx25-pdk -device fsl,,imx25 ** ERROR:/home/thuth/devel/qemu/tcg/tcg.c:538:tcg_register_thread: assertion failed: (n < max_cpus) The imx25-pdk board (which is the one that uses this CPU type) only supports one CPU, and the realize function of the "fsl,imx25" device also uses serial_hds[] directly, so this device clearly can not be instantiated twice and thus we should mark it with user_creatable = 0.
