>Description:
Booting TX3922-based system with ohci-driver enabled gives following:

ohci0: OHCI version 1.0
extent_alloc_subregion: extent `MCS0', size 0x40000, boundary 0x1000
panic: extent_alloc_subregion: bad boundary

>How-To-Repeat:
booting the system...
>Fix:
Dunno, maybe we do not need boundary at all, but I fixed it conditionally in 
.../hpcmips/dev/plumohci.c in function __plumohci_dmamem_alloc:

        /*
         * Allocate buffer from V-RAM area.
        */
        
        if(size > OHCI_PAGE_SIZE) {
            error = bus_space_alloc(sc->sc.iot, PLUM_OHCI_SHMEMBASE,
                PLUM_OHCI_SHMEMBASE + PLUM_OHCI_SHMEMSIZE - 1,
                size, OHCI_PAGE_SIZE, size,  0,
                (bus_addr_t *)(void *)&caddr, &bsh);
        } else {
            error = bus_space_alloc(sc->sc.iot, PLUM_OHCI_SHMEMBASE,
                PLUM_OHCI_SHMEMBASE + PLUM_OHCI_SHMEMSIZE - 1,
                size, OHCI_PAGE_SIZE, OHCI_PAGE_SIZE, 0,
                (bus_addr_t *)(void *)&caddr, &bsh);
        }
        if (error)
                return (1);
