This patch does 'savedefconfig' for exynos_defconfig to remove useless

ignored because of the dependencies even they are enabled in defconfig
file manually. So checking the dependencies would be better.

Enabling Exynos DRM IOMMU support for Exynos is currently broken and
causes a BUG on exynos-iommu driver. This was not an issue since the
options was disabled in exynos_defconfig but after commit 8dcc14f8
("drm/exynos: IOMMU support should not be selectable by user"), it is
selected if EXYNOS_IOMMU is enabled which is in exynos_defconfig.

So a kernel built using exynos_defconfig after the mentioned commit
fails to boot [0]. Disable IOMMU support in Exynos defconfig until
things get sorted out.

The Exynos System-on-Chips have ~7 distinctive I2C IO ports (exact
number depends on chip). However some integrated circuits on board, also
using I2C protocol for communication, can be connected to the SoC by
other GPIO. Enabling the I2C GPIO driver allows using such additional
integrated circuits.

An example of such chip using I2C and connected over GPIO to SoC is
Maxim 77693 MUIC on Trats2 board. The regulator driver of Maxim
77693 offers charger and safeout LDO (necessary for USB OTG).

Actually, we are not able to get arndale-octa board to boot
and mount an MMC partition without this change.

Commit 29824c16 ("USB: host: Rename ehci-s5p to ehci-exynos")
renamed the config entry of EHCI host driver. Similar change needs
to be done in exynos_defconfig as well.

S2MPS11 voltage regulator is commonly used on the latest Exynos
boards like SMDK5420, Arndale-Octa, etc. Hence it makes sense to
enable it like S5M8767A voltage regulator.

Current CONFIG_NR_CPUS value (2) is too small for:
- EXYNOS4412 (4 cores)
- EXYNOS5440 (4 cores)
- EXYNOS5410 (8 cores)
- EXYNOS5420 (8 cores)

Set CONFIG_NR_CPUS to 8 so it is correct for all currently
supported SoCs.

Many of the boards use GPIO-mapped buttons for generic input.
For Arndale board, these buttons also serve as wakeup source.

And the issues reported in commit 522ccdb6 ("ARM: dts:
Disable the RTC by default on exynos5") are no longer reproduced
on EXYNOS5250 based systems. Hence it would be better to re-enable
RTC support for EXYNOS5250.

This turns on a number of configs that are useful on the Chromebook, but also
good to have on in general:

* USB host and MMC drivers(!)
* I2C GPIO arbitration driver
* CYAPA trackpad driver
* simplefb
* CROS EC and keyboard drivers
* S5M8767 driver
* MAX77686 drivers
* MAX8997 driver
* DEVTMPFS + mount
* DM_CRYPT (as module)
* CRYPTOLOOP
* HIGHMEM
* PRINTK timestamps

This also turns off DEBUG_LL, and switches the hardcoded Samsung lowlevel
uart to uart 3 (which is only used to show the "uncompressing kernel"
message at boot, it seems).

This enables the new EXYNOS5 platforms in the defconfig, and enables DT
support on EXYNOS4.

Other options enabled: USB host, EXT3/4, regulators and tps65090,
networking and a few of the common usb ethernet adapters as well as the
smsc911x controller used on some boards.

I enabled EFI_PARTITION, since it's used on some filesystem images I'm
using. I didn't see a need to keep Solaris and BSD partition format
still enabled.

Finally, framebuffer console, logo and fonts were enabled.

Note that enabling some of these options introduces build coverage
previously missing, thus introducing a few build errors and warnings
for which fixes have been sent out already.

[kgene.kim@samsung.com: restored exynos4_defconfig from original]
Signed-off-by: NKukjin Kim <kgene.kim@samsung.com>

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
