26fbe9e531 mx6sabresd: Remove empty reset_cpu()
There is really no need to provide an empty reset_cpu() implementation,
so just remove it.

f2ff834365 imx: mx6: ddr init MMDC according to ddr_type
To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg
to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper.
The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg
when ddr_type is for DDR3. Later we can use ddr_type to initialize
MMDC for LPDDR2.

Initialize ddr_type for different boards which enable SPL.

155fa9af95 spi: mxc: fix sf probe when using mxc_spi
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:

cs = (cs | gpio << 8)

This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".

This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.

Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.
