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.

5b8e76c35e powerpc, 8xx: remove support for 8xx
There was for long time no activity in the 8xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8xx,
so remove it (with a heavy heart, knowing that I remove

604c7d4a5a common/lcd_console: introduce display/framebuffer rotation
Sometimes, for example if the display is mounted in portrait mode or even if it
is mounted landscape but rotated by 180 degrees, we need to rotate our content
of the display respectively the framebuffer, so that user can read the messages
which are printed out.

For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.

If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

7bf71d1f55 lcd: split splash code into its own function
lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.

Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
  lcd_clear() (which is arguably not the correct name for housing such
  code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
  lcd_clear() too.

	return (void *)((ulong)lcd_base + BMP_LOGO_HEIGHT * lcd_line_length);
 #else
	return (void *)lcd_base;
 #endif

This return value gets assigned to lcd_console_address.
lcd_console_address is not assigned or modified anywhere else.
Thus:

 #if defined(CONFIG_LCD_LOGO) && !defined(CONFIG_LCD_INFO_BELOW_LOGO):
	y' = BMP_LOGO_HEIGHT + y;
	lcd_base + y' * lcd_line_length ==
	lcd_base + (BMP_LOGO_HEIGHT + y) * lcd_line_length ==
	lcd_base + BMP_LOGO_HEIGHT * lcd_line_length + y * lcd_line_length ==

	lcd_base + y * lcd_line_length == lcd_console_address + y * lcd_line_length

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

ecfdcee5d9 powerpc: remove orphaned boards mcc200 and prs200
mcc200 and prs200 are old and have no maintainer. Remove the boards.

This also removes the mcc200 specific 1bpp BMP support from
common/lcd.c

2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

a305fb155e lcd: support displaying 24bpp BMPs on >= 24bpp LCDs
most todays LCDs support 32bpp e.g. the framebuffer memory is 32bpp
organized.

To support 24bpp BMPs we need to take only 3 byte from the bpp and set
one byte from the FB to 0.

8d9eaafdd1 lcd: cleanup unused functions
This patch removes following two functions:
- lcd_getbgcolor(...)
  not used somewhere outside lcd.c, internally we use now the global
  variable lcd_color_bg (was return value of function before)
- lcd_getfgcolor(...)
  not used in any place of u-boot

709ea543b9 stdio: Pass device pointer to stdio methods
At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.

For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.

Instead, add a stdio_dev pointer to each of the stdio member functions.

Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.
