[Qemu-devel] [PATCH 4/4] nvdimm: build FIT in nvdimm_build_acpi

[Wei Yang]

Currently we initialize nvdimm device like below:

    device_set_realized
        dc->realize
        nvdimm_plug
            nvdimm_build_fit_buffer
    acpi_build
        nvdimm_build_acpi

This shows nvdimm's acpi stuff is prepared in two places:

    * device plug stage
    * acpi_build stage

It would be more proper to build fit buffer in nvdimm_build_acpi, which
consolidate all acpi related initialization together.

This patch moves FIT build in nvdimm_build_acpi.
