4d979bfdbc common: Move and rename CONFIG_SYS_SUPPORT_64BIT_DATA
This is not really a CONFIG since it is not intended to be set by boards.
Move it into the compiler header with other similar defines, and rename
it.

9bb746d819 spl: Avoid checking for Ctrl-C in SPL with print_buffer()
We don't have a console in SPL so it doesn't make sense to check for
Ctrl-C when printing a memory dump. Skip this so that print_buffer() can
be used in SPL.

6c74e94a65 lib/display_options: avoid illegal memory access
display_options_get_banner_priv() overwrites bytes before the start of the
buffer if the buffer size is less then 3. This case occurs in the Sandbox
when executing the `ut_print` command.

Correctly handle small buffer sizes. Adjust the print unit test to catch
when bytes before the buffer are overwritten.

f60662de77 lib: Allow using display_buffer() in SPL
At present this function uses printf() format strings that are not
supported in SPL, so the output just consists of %llx strings on 64-bit.

dee37fc99d Remove <inttypes.h> includes and PRI* usages in printf() entirely
In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

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.

e9015b304a lib/display_options: Fix print_freq
Build without CONFIG_SPL_SERIAL_SUPPORT does not print the cpu freq.
I have seen this in the odroid U3 board, where on boot one sees this:
CPU:   Exynos4412 @  GHz
instead of:
CPU:   Exynos4412 @ 1 GHz

I am assuming that this change was done to get rid of compiler
warnings related to unused variables when building with
CONFIG_SPL_SERIAL_SUPPORT not being defined in an SPL build.

64419e4751 print_buffer: optimize & shrink
Applying a little creative format string allows us to shrink the initial
data read & display loop by only calling printf once.  Re-using the local
data buffer to generate the string we want to display then allows us to
output everything with just one printf call instead of multiple calls to
the putc function.

The local stack buffer needs increasing by 1 byte, but the resulting code
shrink and speed up is worth it I think.

52dbac69c2 fix print_size printing fractional gigabyte numbers on 32-bit platforms
In print_size(), the math that calculates the fractional remainder of a number
used the same integer size as a physical address.  However, the "10 *" factor
of the algorithm means that a large number (e.g. 1.5GB) can overflow the
integer if we're running on a 32-bit system.  Therefore, we need to
disassociate this function from the size of a physical address.
