[Qemu-devel] [PATCH v5 4/6] hw/arm: add a new modify_dtb_opaque field in arm_boot_info

[Eric Auger <eric.auger@linaro.org>]

This field can be used by any modify_dtb() function to pass
additional arguments requested to build the modified dtb. This
is needed for creating the platform bus dynamic sysbus nodes.
