This series of patches will build Heterogeneous Memory Attribute Table (HMAT)
according to the command line. The ACPI HMAT describes the memory attributes,
such as memory side cache attributes and bandwidth and latency details,
related to the Memory Proximity Domain.
The software is expected to use
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().
