[coreboot] Fam10 error

coreboot-builds/amd_mahogany_fam10/make.log:src/cpu/amd/model_10xxx/fidvid.c:758:
warning: 'fid_max' may be used uninitialized in this function

static void init_fidvid_ap(u32 bsp_apicid, u32 apicid, u32 nodeid, u32 coreid)
...
    u32 fid_max;
...
    	/* fid setup is handled by the BSP at the end. */

} else {	/* ! nb_cof_vid_update */
    	/* Use max values */
    	if (pvimode)
    		UpdateSinglePlaneNbVid();
    }

send = (nb_cof_vid_update << 16) | (fid_max << 8);
    send |= (apicid << 24);	// ap apicid

// Send signal to BSP about this AP max fid
    // This also indicates this AP is ready for warm reset (if required).
    lapic_write(LAPIC_MSG_REG, send | 1);

So we send garbage to the BSP for fid_max of the AP.  What should we
be sending instead if !nb_cof_vid_update?

Thanks,
