Tom Rini 67f51b40ca compiler*.h: sync include/linux/compiler*.h with Linux 5.7-rc5
Copy these from Linux v5.7-rc5 tag.

This brings in some handy new attributes and is otherwise important to
keep in sync.

We drop the reference to smp_read_barrier_depends() as it is not
relevant on the architectures we support at this time, based on where
it's implemented in Linux today.  We drop the call to kasan_check_read()
as that is not relevant to U-Boot as well.

Simon Glass 07bc873c73 ctags: Minor changes to fix ctags output
At present ctags emits lines with unmatched quotes which means that the
output file is invalid. This is with exuberant-ctags version 5.9~svn201103
but I also see it with plain ctags. I am not sure that it is a bug though.

Make a few minor changes in the source code to fix this problem.

Tom Rini 9b2c282b34 compiler*.h: sync include/linux/compiler*.h with Linux 4.5-rc6
Copy these from Linux v4.5-rc6 tag.

This is needed so that we can keep up with newer gcc versions.  Note
that we don't have the uapi/ hierarchy from the kernel so continue to
use <linux/types.h>

Jeroen Hofstee 0a5051ce6e compiler_gcc: prevent redefining attributes
The libc headers on FreeBSD and likely related projects as well contain an
header file, cdefs.h which provides similiar functionality as linux/compiler.h.
It provides compiler independent defines like __weak __packed, to allow
compiling with multiple compilers which might have a different syntax for such
extension.

Since that header file is included in multiple standard headers, like stddef.h
and stdarg.h, multiple definitions of those defines will be present if both are
included. When compiling u-boot the compiler will warn about it hundreds of
times since e.g. common.h will include both files indirectly.

commit 7ea50d5284 "compiler_gcc: do not redefine
__gnu_attributes" prevented such redefinitions, but this was undone by commit
fb8ffd7cfc "compiler*.h: sync
include/linux/compiler*.h with Linux 3.16".

Add the checks back where necessary to prevent such warnings.

As the original patch this checkpatch warning is ignored:
"WARNING: Adding new packed members is to be done with care"

Masahiro Yamada fb8ffd7cfc compiler*.h: sync include/linux/compiler*.h with Linux 3.16
Copy them from Linux v3.16 tag.
My main motivation of this commit is to add compiler-clang.h.

Jeroen Hofstee 7ea50d5284 compiler_gcc: do not redefine __gnu_attributes
gcc allows extensions to be non compiler specific by defining
__* macros for the attributes supported by gcc. Having a
different definition causes many warnings during the build
(cdefs.h on FreeBSD uses __attribute((__pure__)) where u-boot
uses __attribute__((pure)) for example). Do not redefine
these macros to suppress these warnings.

This patch ignores the checkpatch warning:
WARNING: __packed is preferred over __attribute__((packed))

Graeme Russ 95ffaba390 x86: Fix support for booting bzImage
Add support for newer (up to 2.6.33) kernels

Add zboot command which takes the address of a bzImage as its first
argument and (optionally) the size of the bzImage as the second argument
(the second argument is needed for older kernels which do not include
the bzImage size in the header)
