00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

a5bfb4ff9e imx: ventana: add dt fixup for watchdog external reset
Added removal of the fsl,ext-reset-output property in the wdog node for board
revisions that pre-date the addition of the external watchdog reset signal.

This property is a recent addition to mainline linux kernel in order to
specify that the IMX watchdog external reset should be used instead of the
internal chip-level reset.

5a08ad6fdc imx: ventana: add dt fixup for GW16082 irq mapping
The GW16082 mini-PCI expansion mezzanine uses a TI XIO2001 PCIe-to-PCI
bridge with legacy INTA/B/C/D interrupts. These interrupts are assigned
in the reverse order according to the PCI spec.

If the TI bridge is found on the Ventana PCI bus, add device-tree nodes
according to bus enumeration explicitly defining the interrupt mapping
to override the default PCI mapping in the Linux kernel. This allows
the GW16082 to work with upstream kernels that support device-tree
irq parsing.

34b080b79c imx: ventana: add fdt fixup to enable UHS-I support on selected boards
UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. For backwards compatibility to not break users
who have old bootloaders and newer kernels the device-tree on boards with
microSD disables UHS-I support by default by defining the no-1-8-v property
in the esdhc controller node. For models/revisions that support switchable
1.8V/3.3V I/O which is detectable by the presence of a pull-down on the
SD3_VSELECT pin we remove that property to enable support in the kernel.

Additionally we add SD3_VSELECT to the pinmux for clarity (even though U-Boot
does not currently support UHS-I modes requiring 1.8V I/O).

f17a9af846 imx: ventana: enable pwm device-tree property based on hwconfig
Most Ventana boards have a connector with off-board digital-I/O signals
including some that can be pinmuxed as either a PWM or a GPIO. The hwconfig
env variable is used to configure these and they will be pinmuxed according
to this configuration in the bootloader.

This patch adds a device-tree fixup that will enable the pwm controller
nodes appropriately for digital-I/O's that are configured as pwm via hwconfig
so that the pin can be used with the Linux kernel /sys/class/pwm API.
