Kill unneeded #include <linux/kconfig.h>

Because the top-level Makefile forces all the source files
to include include/linux/kconfig.h (see the UBOOTINCLUDE define),
these includes are redundant.

Kill unneeded #include <linux/kconfig.h>

Because the top-level Makefile forces all the source files
to include include/linux/kconfig.h (see the UBOOTINCLUDE define),
these includes are redundant.

By the way, there are exceptions for the statement above; host
programs. In fact, host tools in U-Boot depend on a particular
board configuration, although I think they should not. So, some
files still include <linux/config.h> to work around build errors
on host tools.

sunxi: Make DRAM_ODT_EN Kconfig setting a bool

Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION
setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of
only in dram_sun4i.c and hardcoding odt_en elsewhere.

Note this commit makes no functional changes for existing boards,
its purpose is to allow changing the odt_en value on future A33 boards.

For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs
currently do) this patch turns on odt for both the DQ and the DQS lines,
whereas previously it was possibly (but not desirable) to turn odt on only
for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

sunxi: dram: Optionally use standard JEDEC timings for sun[457]i

In addition to the current Android magic settings, allow to optionally use
DDR3 timing parameters, which are tailored for different clock frequencies
and JEDEC speed bins. This should improve reliability and performance.

Adding '+S:CONFIG_DRAM_TIMINGS_DDR3_1066F_1333H=y' to the board defconfig
allows to use timings, which are calculated for the DDR3-1066F speed bin.
A lot of DDR3 chips, which are used in real Allwinner based devices,
support DDR3-1066F speed bin timings.

And adding '+S:CONFIG_DRAM_TIMINGS_DDR3_800E_1066G_1333J=y' should work
with any DDR3 chips, because this targets the slowest JEDEC speed bins.

The vendor magic values are still used by default for DRAM, but board
maintainers now have more flexibility in DRAM timings selection.

sunxi: Stop differentiating between 512M and 1G variants of the same board

While working on adding more boards I noticed that we lack a config for
the 512M cubieboard, and that some of the new boards which I want to add also
have 512M and 1G variants, rather then adding 2 defconfig's for all of these,
lets switch the exising boards which have both a 512M and 1024M variant over
to the sun4i dram autoconfig code.

This also drops the foo_RAMSIZE_defconfig variants of boards where we currently
have 2 separate configs already.

Note:
1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with
a value other then its default for now, but we need this to be configurable
to support some new boards with auto dram config.

2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match
the defaults, this is done to make it more clear what values are used for a
certain board.

This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G
variants, the dram autoconfig code has also been tested on a 512M mk802
(a defconfig for the mk802 is added in a later patch).
