4717e1395e imx: ventana: set LTC3676 PMIC to appropriate values per datasheet
The IMX6 Datasheets specifies that when the IMX6 LDO is enabled
(internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to
provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive)
and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV
shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.

3a7577e5f3 gw_ventana: Use the generic spl_sd.cfg
gw_ventana can boot from SPI or NAND and both of these interfaces boot from
the same 0x400 offset.

This means that we could simplify the code and replace the custom gw_ventana.cfg
with the generic spl_sd.cfg, as it provides the same boot offset of 0x400.

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:

CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

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.

c91e4b8b08 imx: ventana: base SPL MMDC calibration on width and size not board
The IMX6 MMDC calibration registers depend on propagation delay and capacitive
loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the
board layout varies little in trace-lengths such that propagation delays are
irrelevant thus we can simply things by using calibration values obtained
from various board layouts based on a common SoC and DDR chip configuration.

This eliminates board-model from being needed allowing more flexibility. These
values were tested on a large sample size of Gateworks Ventana boards ranging
in layout, and memory configuration over the entire temperature range supported.

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

0a11d6f29c mx6: Remove duplication of iomuxc structure
There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.
