in drivers/ata/libata-sff.c:
...
#if defined(CONFIG_NO_ATA_LEGACY)
/* Some platforms with PCI limits cannot address compat
port space. In that case we punt if their firmware has
left a device in compatibility mode */
if (legacy_mode) {
printk(KERN_ERR "ata: Compatibility mode ATA is not supported on this platform, skipping.\n");
return -EOPNOTSUPP;
}
#endif
...
there is no Kconfig file that defines that variable -- should that
test be removed? or is something eventually coming that defines it?

It is used by some of the unsubmitted tree stuff certainly and is there
because some platforms will need it (eg FRV).

ok, good enough, i'm just trying to cull my list of unreferenced
Kconfig variables.
