Hi, When I'm trying to increase boot_img_sizes, it reports error like

During handling of the above exception, another exception occurred:

The issue is partition_size is hard coded in https://android.googlesource.com/platform/system/tools/mkbootimg/+/master/gki/generate_gki_certificate.py#35 to be 64MB while boot_img_sizes in gki_artifacts can be modified .

    avbtool_cmd = [
        avbtool, 'add_hash_footer',
        '--partition_name', name,
        '--partition_size', str(64 * 1024 * 1024),
        '--image', image,
        '--algorithm', algorithm,
        '--key', key,
        '--do_not_append_vbmeta_image',
        '--output_vbmeta_image', output,
    ]

Can you fix?

Thx Joey
