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.

As mx6sabreauto supports SPL now, all variants can boot using the same
defconfig.
This patch:
- Removes non-SPL targets.
- Renames target to mx6sabreauto_defconfig.
- Renames folder and board files to mx6sabreauto.
- Updates MAINTAINERS, Makefile and Kconfig accordingly.
- Removes .cfg files.
- Adds a README with instructions to build and flash SPL and u-boot.img.

Currently the following build error is seen when a board using MMC SPL

i.MX 6UL and 6ULL have different boot device capabilities and
use therefor use a different boot device selection table than
other i.MX 6 devices. Particularly, the value which has been
used so far (b0001) is assigned to QSPI boot for these two
devices.
There is no common reserved value for all i.MX 6devices. Use
b0010 for i.MX 6UL and 6ULL via compile time ifdef.

Logic PD has an i.MX6Q system on module (SOM) with a development kit. The
SOM has a built-in microSD socket, DDR and NAND flash. The development kit
has an SMSC Ethernet PHY, serial debug port and a variety of peripherals.
This have been verified to boot the i.MX6Q version over either SD
on the development kit or NAND built into the SOM. Items in the dtsi file
are specific to the SOM itself. Items in the dts file are in the baseboard.
Future versions of the SOM will come out supporting the same basebord and
potentially future base boards will come out supporting the same SOM.

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.
During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will
make the code more readable. Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.
This commit was created as follows:
[1] Edit "default n" to "default y" in the config entry in
common/Kconfig.
[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"
[3] Rename the instances in defconfigs by the following:
find . -path './configs/*_defconfig' | xargs sed -i \
-e '/CONFIG_SYS_NO_FLASH=y/d' \
-e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'
[4] Change the conditionals by the following:
find . -name '*.[ch]' | xargs sed -i \
-e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
-e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
-e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
-e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'
[5] Modify the following manually
- Rename the rest of instances
- Remove the description from README
- Create the new Kconfig entry in drivers/mtd/Kconfig
- Remove the old Kconfig entry from common/Kconfig
- Remove the garbage comments from include/configs/*.h

The DDR calibration routines are gated by conditionals for the
i.MX6DQ SOCs, but with the use of the sysinfo parameter, these
are usable on at least i.MX6SDL and i.MX6SL variants with DDR3.
Also, since only the Novena board currently uses the dynamic
DDR calibration routines, these routines waste space on other
boards using SPL.
Add a KConfig entry to allow boards to selectively include the
DDR calibration routines.

Add routine mmdc_read_calibration() to return the output of DDR
calibration. This can be used for debugging or to aid in construction
of static memory configuration.
This routine will be used in a subsequent patch set adding a virtual

during an initial production run.

The DDR calibration routines have scattered support for bus
widths other than 64-bits:
-- The mmdc_do_write_level_calibration() routine assumes the
presence of PHY1, and
-- The mmdc_do_dqs_calibration() routine tries to determine
whether one or two DDR PHYs are active by reading MDCTL.
Since a caller of these routines must have a valid struct mx6_ddr_sysinfo
for use in calling mx6_dram_cfg(), and the bus width is available in the
"dsize" field, use this structure to inform the calibration routines which
PHYs are active.
This allows the use of the DDR calibration routines on CPU variants
like i.MX6SL that only have a single MMDC port.
