[Qemu-devel] [PULL v6 02/12] hw/arm: simplify arm_load_dtb

[Eduardo Habkost <ehabkost@redhat.com>]

From: Tao Xu <tao3.xu@intel.com>

In struct arm_boot_info, kernel_filename, initrd_filename and
kernel_cmdline are copied from from MachineState. This patch add
MachineState as a parameter into arm_load_dtb() and move the copy chunk
of kernel_filename, initrd_filename and kernel_cmdline into
arm_load_kernel().
