I just see (probably Ubuntu contributed code) at libdebian-installer:

static const char *supported_generic_subarches[] = {
    "dove",
    "omap",
    "omap4",
    "mx51",
    NULL
};

and machine mappings has:
    { "Freescale MX51 Babbage Board", "imx5" }, /* iMX51 reference hardware. */

Would it break 'others' configurations if we set/change 'mx5' as
subarchitecture, which seems to be the most reasonable one at the
moment.
