As part of testing booting Linux kernels on Rockchip devices, it was
discovered by Ziyuan Xu and Sandy Patterson that we had multiple and for
some cases incomplete isb definitions. This was causing a failure to
boot of the Linux kernel.
In order to solve this problem as well as cover any corner cases that we
may also have had a number of changes are made in order to consolidate
things. First, <asm/barriers.h> now becomes the source of isb/dsb/dmb
definitions. This however introduces another complexity. Due to
needing to build SPL for 32bit tegra with -march=armv4 we need to borrow
the __LINUX_ARM_ARCH__ logic from the Linux Kernel in a more complete
form. Move this from arch/arm/lib/Makefile to arch/arm/Makefile and add
a comment about it. Now that we can always know what the target CPU is
capable off we can get always do the correct thing for the barrier. The
final part of this is that need to be consistent everywhere and call
isb()/dsb()/dmb() and NOT call ISB/DSB/DMB in some cases and the
function names in others.

Update several boards to use driver model for video. This involves changes
to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration
since they use the device tree settings in the same way as Linux.
Boards converted are:
- snow
- spring
- peach-pit
- peach-pi
All have been tested. Not converted:
- MIPI display driver
- s5pc210_universal
- smdk5420
- smdk5250
- trats
- trats2

The existing Exynos 32-bit platform support needs to be realigned in
order to support newer 64-bit Exynos platforms. The driver model will
be utlized for drivers on the 64-bit Exynos platforms and so some of
the older platform support code would not be required for the newer
64-bit Exynos platforms.

This commit adds driver for Exynos54xx ADC subsystem.
The driver is implemented using driver model, amd provides
ADC uclass's methods for ADC single channel operations:
- adc_start_channel()
- adc_channel_data()
- adc_stop()
The basic parameters of ADC conversion, are:
- sample rate: 600KSPS
- output the data as average of 8 time conversion
ADC features:
- sample rate: 600KSPS
- resolution: 12-bit
- channels: 10 (analog multiplexer)

The proper CPU ID for those Exynos variants is 0x5422,
but before the 0x5800 was set. This commit fix this back.
Changes:
- set cpu id to 0x5422 instead of 0x5800
- remove macro proid_is_exynos5800()
- add macro proid_is_exynos5422()
- change the calls to proid_is_exynos5800() with new macro

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.
