Add DWMCI_QUIRK_DISABLE_FMP which disables Flash Memory Protector (FMP)
during driver's init. It's usually done by early bootloaders, but in
some cases (like USB boot) the FMP may be left unconfigured. The issue
was observed on Exynos850 SoC (the E850-96 board). Enabling this quirk
makes eMMC functional even in such cases.
No functional change, as this feature is only added here but not enabled
for any chips yet.

Add the compatible entry and corresponding chip data for Exynos7
compatible chips, which covers modern ARM64 based Exynos chips. They
have some differences w.r.t. old ARM32 Exynos chips:
- CLKSEL register offset is different
- 64-bit IDMAC descriptor and 64-bit IDMAC registers are used
(implemented in dw_mmc core driver)
In terms of the driver implementation, the CIU clock is obtained via CCF
framework (as opposed to ad-hoc clock driver implementation for ARM32
chips).

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

The sev() and wfe() asm macros are currently defined only for
mach-exynos. As these are common Arm instructions, move them to the
common asm/system.h header file, for both Armv7 and Armv8, so they
can be used by other machines.
wfe may theoretically trigger a context switch if an interrupt occurs
so add a memory barrier to this call.

- None of the callers perform error checking and based on the non-empty
versions of this function, there's no checking to be done, so make
this a void.
- Add a default weak version of the function.

The way that the timer support is currently done for exynos/nexell
platforms relies on the legacy PWM infrastructure, and that needs to be
updated. However, we really cannot safely undef CONFIG_DM_PWM to build
the timer.c file without warnings. For now, rename the relevant legacy
functions to be prefixed with s5p_ and add prototypes to the arch pwm.h
files.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

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.

to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration

- snow
- spring
- peach-pit
- peach-pi
All have been tested. Not converted:
- MIPI display driver
- s5pc210_universal

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.

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.
