even thought I have no doc to now what would means:
        res->start =3D (unsigned long)(signed) READ_U32(ioaddr) << 16; (=3D=
=3D
0x0 in 32bits)
        res->end =3D (unsigned long)(signed) (READ_U32(ioaddr + 4) << 16)=
 -
1; (=3D=3D 0xffffffff in 32bits too)

but seems that test:
        if (res->end + 1 =3D=3D res->start)
is a stuff which not love 64bit :-(

Any idea?

Thanks,

if I well understand only 3 resources initialized?
