72fa1ad8d9 log: Allow padding of the function name
At present when function names are logged, the output is a little hard to
read since every function is a different length. Add a way to pad the
names so that the log messages line up vertically. This doesn't work if
the function name is very long, but it makes a big difference in most
cases.

Use 20 characters as a default since this covers the vast majority of
functions.

58b4b7133a log: Add support for logging a buffer
The print_buffer() function is very useful for debugging. Add a version
of this in the log system also.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

6278ec1919 test: add LOGL_FORCE_DEBUG flags support in log tests
Add a check of the _log function with LOGL_FORCE_DEBUG flags,
used to force the trace display.

The trace should be displayed for all the level when flags
have LOGL_FORCE_DEBUG bit is set, for any filter.

62ef81891d test: log: Convert log_test from python to C
When rebasing this series I had to renumber all my log tests because
someone made another log test in the meantime. This involved updaing a
number in several places (C and python), and it wasn't checked by the
compiler. So I though "how hard could it be to just rewrite in C?" And
though it wasn't hard, it *was* tedious. Tests are numbered the same as
before to allow for easier review.

A note that if a test fails, everything after it will probably also fail.
This is because that test won't clean up its filters.  There's no easy way
to do the cleanup, except perhaps removing all filters in a wrapper
function.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

cdd140af5c log: Add helpers for common log levels
At present to output a log message you need something like:

   log(UCLASS_SPI, LOCL_INFO, "message1");
   log(UCLASS_SPI, LOCL_INFO, "message2");

but many files use the same category throughout. Also it is helpful to
shorten the length of log names, providing helpers for common logging
levels. Add some macros so that it is possible to do:

   (top of file, before #includes)
   #define LOG_CATEGORY UCLASS_SPI

   (later in the file)
   log_info("message1");
   log_debug("message2");
   log_err("message3");

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.
