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.

00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

eb3c0cf806 videomodes: Add helper functions to parse video-mode env-var extra options
Add 2 helper functions to get strings, respectively integers from the options
value returned by video_get_video_mode() / video_get_ctfb_res_modes().

e976b868f2 videomodes: Add video_get_ctfb_res_modes helper function
Add a video_get_ctfb_res_modes() helper function, which uses
video_get_video_mode() to parse the 'video-mode' environment variable and then
looks up the matching mode in res_mode_init and returns the matching mode.

92a88c33f0 videomodes: Add (vesa) standard timings
The timings for the modes defined in videomodes.c differ (significantly)
from vesa standard timings for these modes.

This commit adds a version with the proper std timings for these modes,
since I do not want to cause regressions, boards which want to use the standard
timings need to define CONFIG_VIDEO_STD_TIMINGS to get the new correct timings.

Since there is no std timing for 960x720 this commit uses the timing used
by the nvidia video drivers for 960x720, which uses a standard pixelclock
of 74.25 MHz rather then the weird 76.335... clock used by the old modes.

0c91d25767 videomodes: Add pixelclock_khz and refresh fields to ctfb_res_modes
Add pixelclock_khz and refresh fields to ctfb_res_modes:

1) pixelclocks are usually referred to in hz, not picoseconds, and e.g
pll-s are also typically programmed in hz, not ps. Converting between the
2 leads to rounding differences, add a pixelclock_khz field to directly
store the *exact* pixelclock for a mode, so that drivers do not need to
resort to rounding tricks to try and guess the exact pixelclock;

2) The video-mode environment variable, as parsed by video_get_video_mode
also contains the vertical refresh rate, add a refresh field, so that
the refresh-rate can be matched when parsing the video-mode environment
variable.

a5dbdc81ea video: parse the video-mode environment variable
Add function video_get_video_mode(), which parses the "video-mode" environment
variable and returns each of its components.  The format matches the video=
command-line option used for Linux:

	video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>

	<driver> The video driver, ignored by U-Boot
	<xres> The X resolution (in pixels) to use.
	<yres> The Y resolution (in pixels) to use.
	<depth> The color depth (in bits) to use.
	<freq> The frequency (in Hz) to use.
	<options> A comma-separated list of device-specific options
