e3245e4254 video: simplefb: Remove DM_FLAG_PRE_RELOC flag
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

7d121a8ea4 sunxi: use 6MHz PLL_VIDEO step for DE2 for higher resolution LCD
DE2 SoCs can support LCDs up to 1080p (e.g. A64), and 3MHz step won't
let PLL_VIDEO be high enough for them.

Use 6MHz step for PLL_VIDEO when using DE2, to satisfy 1080p LCD.

55d39911c0 sandbox: video: Speed up video output
At present there are many situations where sandbox syncs the display to

needed every now and then. Update video_sync() so that we can specify
whether this operation is really needed.

At present this flag is not used on other architectures. It could also
be used for reducing writeback-cache flushes but the benefit of that would
need to be investigated.

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.

02325c7bfd treewide: fix up files incorrectly marked executable
Inspired by the following kernel commit:

"commit 90fda63fa1156ec1bcfd7f9ca384cec221f70a21
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Sat Apr 7 13:31:23 2018 -0700

treewide: fix up files incorrectly marked executable

Joe Perches noted that we have a few source files that for some
inexplicable reason (read: I'm too lazy to even go look at the history)
are marked executable:

drivers/gpu/drm/amd/amdgpu/vce_v4_0.c
drivers/net/ethernet/cadence/macb_ptp.c

A simple git command line to show executable C/asm/header files is this:

   git ls-files -s '*.[chsS]' | grep '^100755'

and then you can fix them up with scripting by just feeding that output
into:

  | cut -f2 | xargs chmod -x

and commit it.

Which is exactly what this commit does.
