0b03a931ab omap: hsmmc: assume cd gpio is active low
Switch the default CD GPIO polarity to active low.

The current hsmmc driver assumption that the CD GPIO is active high, but
in the real hardware, usually the opposite holds.
The usual SD card socket has a mechanical switch which is grounded as
soon as a card is inserted.
Of course there might be some board logic which inverts the signal, but
as far as current users are concerned, there is no such logic.

Current U-Boot users either not using the CD functionality, or have a
different way (e.g. external to SoC GPIO controller) for checking the
card presence.

This patch also brings the polarity assumption in line with the Linux
kernel and adds appropriate comments.

This patch also might spare issues once the TWL GPIO driver will be
converted to the DM.

f4a40f05f5 omap3: cm-t35: extract the splash code from board
The splash screen loading code can be reused by other compulab boards.
For now extract it to a common location for further reuse.

This also switches the splash code dependency from CONFIG_LCD to
CONFIG_SPLASH_SCREEN as it should normally be.

In addition this patch fixes the accidental dependency of the
get_board_mem_timings() function on CONFIG_LCD, by just moving the
splash code and leaving the above function intact.

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
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.

86256b796e dm: move platform data headers to include/dm/platform_data
The platform_data definitions are generally referenced from both
drivers and board files.  That is why header files defining
platform_data sturectures are placed in "include" directory,
but our top level "include" directory is already too cluttered.

Let's collect platform_data definitions under the directory
"include/dm/platform_data" like Linux gathers ones around under
"include/linux/platform_data".

This commit moves two header files:

  include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h
  include/serial_pl01x.h -> include/dm/platform_data/serial_pl01x.h

Use gpio_request for all the gpios that are utilized by various
subsystems in cm-fx6, and refactor the relevant init functions
so that all gpios are requested during board_init(), not during
subsystem init, thus avoiding the need to manage gpio ownership
each time a subsystem is initialized.

The new division of labor is:
During board_init() muxes are setup and gpios are requested.
During subsystem init gpios are toggled.

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

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/.
