The reserve_contiguous_params function is used to reserve
a set of contiguous PARAMs. If we do not find a complete
set of contiguous PARAMs, the functions still has to free
every PARAM that it found to be free in the process of finding a
complete set and thus marked as "in use".
This patch mainly deals with correctly handling the
freeing of PARAMs.

The edma_alloc_cont_slots API is used for obtaining a set of
contiguous slots. When we use the "_ANY" option with this
API, by definition of this option it is suppossed to start
looking for a set of contiguous slots starting from slot 64 for
DaVinci SOC's and 32 for DA8xx SOC's. This has been explained in
the API description in the driver itself. So when we use the
"_ANY" option with this API, the slot number passed as
an argument should be a "don't care".
This patch takes care of this condition mentioned above.
When checking to see if the starting slot is a valid number,
it checks to make sure that the "_ANY" option is not used.

LCD that's on the User Interface (UI) daughter card of the

The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes. The muxes are controlled by the 'MUX_MODE' line on
the UI card. The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
