19f59ea6db MX6: drop binary constants from iomux header
Constants set with binary value (0b...) are not compiled
from old toolchain when used by the clrsetbits_le32 macro.
Replaces them with the corresponding hex value.

The error reported (for example with the mx6qsabrelite board)
is something like:

mx6qsabrelite.c:369:1: error: invalid suffix "b101" on integer constant
mx6qsabrelite.c:369:1: error: invalid suffix "b10010" on integer constant
mx6qsabrelite.c:369:1: error: invalid suffix "b0000" on integer constant
mx6qsabrelite.c:369:1: error: invalid suffix "b10001" on integer constant

ea00e59be0 MX: set a common place to share code for Freescale i.MX
Up now only MX5 and MX6 can share code, because they have
a common source directory in cpu/armv7. Other not armv7
i.MX can profit of the same shared code. Move these files
into a directory accessible for all, similar to plat-mxc
in linux.

8203b201ea kw_spi: fix clock prescaler computation
The computation was not correct with low clock values: setting a 1MHz

af369d9831 mx5: add iomux-mx51.h include
Allow usage of the imx-common/iomux-v3.h framework by including pad settings
for the i.MX51. The content of the file is taken from Linux kernel at
commit 5d23b39 plus the required changes to make it work in U-Boot.

The contained pad settings are the minimum required to make an Efika MX boot
and get all the currently-implemented peripherals working in U-Boot.

It is recommended that this file not be just a dumping ground for pins but
only contain the settings required for all the boards using it.

Changes for v2:
 * reference commit id from Linux kernel
 * additionally roll in the USB pads
 * removed GPIO_NUMBER define
