Clean up board_f sequence a little
This series tries to remove #ifdefs from the board_f init sequence. It
gets as far as I2C and then we need to discuss whether we can start to
remove the old I2C framework.

I think that ideally each entry in the init sequence should be enabled by
at most one CONFIG, which is in Kconfig and is not arch-specific.

dm: i2c: Add support for multiplexed I2C buses 2015-08-06T03:06:10+00:00 Simon Glass sjg@chromium.org 2015-08-03T14:19:21+00:00 3d1957f0ea0133ec06f9c6fd85dc1acdf66ad29c Add a new I2C_MUX uclass. Devices in this class can multiplex between several I2C buses, selecting them one at a time for use by the system. The multiplexing mechanism is left to the driver to decide - it may be controlled by GPIOs, for example. The uclass supports only two methods: select() and deselect(). The current mux state is expected to be stored in the mux itself since it is the only thing that knows how to make things work. The mux can record the current state and then avoid switching unless it is necessary. So select() can be skipped if the mux is already in the correct state. Also deselect() can be made a nop if required. Signed-off-by: Simon Glass <sjg@chromium.org> 
Add a new I2C_MUX uclass. Devices in this class can multiplex between

The multiplexing mechanism is left to the driver to decide - it may be

The uclass supports only two methods: select() and deselect().

The current mux state is expected to be stored in the mux itself since
it is the only thing that knows how to make things work. The mux can
record the current state and then avoid switching unless it is necessary.
So select() can be skipped if the mux is already in the correct state.
Also deselect() can be made a nop if required.
