91f00ba2c1 sysreset: psci: use psci driver exported functions
Use psci driver exported functions for reset/poweroff, instead of
invoking directly invoke_psci_fn.

857f39d7b0 sysreset: switch to using SYSRESET_POWER_OFF for poweroff
It seems that SYSRESET_POWER_OFF was added recently, and all previous code
used SYSRESET_POWER for poweroff. SYSRESET_POWER is supposed to be a
PMIC-level power cycle, not a poweroff.

(Comment by Simon Glass)
SYSRESET_POWER means to do a power reset (removing and reinstating all power)
SYSRESET_POWER_OFF means to turn the device off and leave it off

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

4af0d7e870 dm: Fix up inclusion of common.h
It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.

Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.

9d922450aa dm: Use dm.h header when driver mode is used
This header includes things that are needed to make driver build. Adjust
existing users to include that always, even if other dm/ includes are
present

573a3811ed sysreset: psci: support system reset in a generic way with PSCI
If the system is running PSCI firmware, the System Reset function
(func ID: 0x80000009) is supposed to be handled by PSCI, that is,
the SoC/board specific reset implementation should be moved to PSCI.
U-Boot should call the PSCI service according to the arm-smccc
manner.

The arm-smccc is supported on ARMv7 or later.  Especially, ARMv8
generation SoCs are likely to run ARM Trusted Firmware BL31.  In
this case, U-Boot is a non-secure world boot loader, so it should
not be able to reset the system directly.
