EXYNOS_IOMMU is disabled in exynos_defconfig since it was known to cause
boot failures on Exynos Chromebooks. The recommendation was for IOMMU to
be enabled manually on systems as needed.
A recent exynos_drm change added a warning message when EXYNOS_IOMMU is
disabled. It is necessary to enable it to avoid the warning messages.
A few initial tests have shown that enabling EXYNOS_IOMMU might be safe
on Exynos Chrome-books.
Due to some other changes in the order of operations during boot
process, power domains are initialized very early and because of the
temporary lack of devices (which are not yet added to the system), are
turned off.
This practically stops FIMD for scanning framebuffer very early during
boot, before IOMMU gets initialized and "solves" the issue, which was
the reason to disable Exynos IOMMU by default on Exynos Snow Chromebooks.

exynos_defconfig, beside serving as a reference config for Exynos-based
devices, is used by developers during regular development work.
Enabling options responsible for locking tests allows to discover bugs
in drivers and mach code earlier.
This enables:
1. Detection of sleeping in atomic sections (DEBUG_ATOMIC_SLEEP),
2. Full lockdep (DEBUG_LOCK_ALLOC and PROVE_LOCKING which makes other
lock debug entries unneeded),
3. Detection of soft, kernel lockups (SOFTLOCKUP_DETECTOR).

Current CMA size of 64 Mbytes is right on the edge of being small when
several drivers need to allocate large CMA buffers.
For example, if the s5p-mfc driver needs to pre-allocate CMA memory to
decode a H.264 1080p video, then there won't be enough CMA memory left
for other drivers, such as the exynos-drm driver that may need to
allocate GEM buffers for the display manager.
Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases
such as these.

The Exynos SoC provides a Security SubSystem block for accelerating some
cryptographic operations. Enable the driver for it - s5p-secss to
utilize the hardware acceleration.
Currently the s5p-secss driver supports AES in CBC and ECB modes.
However on Odroid XU4 (Exynos5422) and Trats2 (Exynos4412) boards this
change introduces one booting error (because of unaligned buffers):
alg: skcipher: encryption failed on chunk test 1 for ecb-aes-s5p: ret=22
The cbc-aes-s5p properly registers itself and passes self-tests.

Enable the kernel NEON mode and asm/NEON accelerated crypto algorithms
which should bring performance benefits on Exynos SoCs. Enable these as
modules because they are optional, not essential anyhow for platform
booting nor related directly to Exynos Soc. All accelerated algorithms
pass booting self-tests on Odroid XU4 (Exynos5422) and Trats2 (Exynos4412).
Additionally enable cpufreq statistics as they are useful for debugging.

Defconfig updates are kept separate from other branches mostly to avoid
conflicts between the different categories (driver branch enabling something
that has context conflict with SoC options, etc).
A lot of this again is scattered across the various hardware platforms.
multi_v7_defconfig, our "generic" config for most 32-bit platforms has
been gone through by Marvell Berlin maintainers and added most options
they need to run on their hardware. Broadcom NSP is also added there,
and the new Atmel SAMA5D2 (added last release). Rockchip also has display
and other devices supported in that config.
In addition to that, the usual small churn of new options being added
here and there.

Mixer driver is selected by CONFIG_DRM_EXYNOS_HDMI option. Since Exynos5433
HDMI does not require Mixer. There will be separate options to select Mixer
and HDMI. Adding new option to defconfig before Kconfig will allow to keep
bisectability.

The Marvell WiFi-Ex driver tries to load a firmware on probe. So if the
driver is built-in and probed before a firmware is available, this is
not loaded and the chip does not work.
This happens for example if an initramfs isn't used since the driver is
probed before the root filesystem is mounted.
Change the default config since the driver isn't needed for machines to
boot and is more convenient to have it enabled as a module to avoid
requiring an initramfs or to have the firmware built into the kernel.

The simplefb driver allows the kernel to render on a pre-allocated
buffer that's been initialized by firmware before the kernel boots.
This option was enabled to have display working on the Exynos5250
Snow Chromebook by commit da9d0fbf5e ("ARM: exynos: defconfig
update") since proper DRM/KMS support did not exist at that time.
But now that the Exynos DRM driver has support for this hardware,
there is no need to have simplefb enabled. In fact, if a user has
a u-boot that injects the simplefb dev node to the FDT before pass
it to the kernel, display won't be properly initialized and only a
blank screen will be shown since there isn't a proper handoff from
the simplefb driver to the Exynos DRM driver.
