This commit corrects print of nomatch (newline was too early) and fix

according to actual system state)

f3e8760ff5 [spibus] add initial placeholders for transfer mode and frequency. 
This doesn't yet implement it in the controllers or the transfer
calls, but it's a start.

Obtained from:	loos (frequency), ray/zrouter (transfer mode)

a0814c1586 Revert r298268 (Add optional chip_select/deselect methods). 
None of supported hardware do require that.

af8c306065 Add optional chip_select/deselect methods. This is required 
when we want to keep CS asserted for multiple transfers.

585300e937 Add an OFW SPI compatible bus. Fix the spibus probe to return 
BUS_PROBE_GENERIC and not BUS_PROBE_SPECIFIC (0) so the OFW SPI bus can
attach when enabled.  Export the spibus devclass_t and driver_t
declarations.

4b7ec27007 - There's no need to overwrite the default device method with the default 
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.
  Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
  Discussed with: jhb
- Also while at it, use __FBSDID.

3d844eddb7 bus_add_child: change type of order parameter to u_int 
This reflects actual type used to store and compare child device orders.
Change is mostly done via a Coccinelle (soon to be devel/coccinelle)
semantic patch.
Verified by LINT+modules kernel builds.

86663fabdd MFp4: when passing the transfer up the foodchain, make sure we go up 
the food chain.  devi == NULL is the error condition.  Treat it as such.

Initial spibus support.  Seems to be OK, but needs some polish.

	# someone should write a bit-bang spi parallel port interface :-)
