It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and
CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less
than a year away.

Also we want to have a CONFIG_I2C for U-Boot proper just like we have
CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules.

Rename this symbol so it is clear it is going away.

Rsync all defconfig files using moveconfig.py
Signed-off-by: NTom Rini <trini@konsulko.com>

This script was broken by the change to default archives for linking.
This is due to objcopy specifically disallowing copying of thin
archives.  To fix this and re-support external users of this script,
switch to using the same logic the u-boot-initial-env make target uses
to dump the section from the object file.

Align Kconfig and Kbuild logic to Linux 4.20 release with minimal impact
on files outside of this scope.

As part of this re-sync, a few related changes from previous Linux
releases were found to have been missed and merged in, and are not in
the following list.

The imported Linux commits are:

Some toolchains are compiled so that they pass a --build-id=something
parameter to the linker implicitly.

This causes U-Boot LTO linking to fail with something like:
  ld: section .note.gnu.build-id LMA ... overlaps section .text LMA ...
because U-Boot's link scripts do not currently handle .note.gnu.build-id
section.

Fix this by explicitly disabling build-id.

Add plumbing for building U-Boot with Link Time Optimizations.

When building with LTO, $(PLATFORM_LIBS) has to be in --whole-archive /
--no-whole-archive group, otherwise some functions declared in assembly
may not be resolved and linking may fail.

Note: clang may throw away linker list symbols it thinks are unused when
compiling with LTO. To force these symbols to be included, we refer to
them via the __ADDRESSABLE macro in a C file generated from compiled
built-in.o files before linking.

Currently we use incremental linking (ld -r) to link several object
files from one directory into one built-in.o object file containing the
linked code from that directory (and its subdirectories).

Linux has, some time ago, moved to thin archives instead.

Thin archives are archives (.a) that do not really contain the object
files, only references to them.

Using thin archives instead of incremental linking
- saves disk space
- apparently works better with dead code elimination
- makes things easier for LTO

The third point is the important one for us. With incremental linking
there are several options how to do LTO, and that would unnecessarily
complicate things.

We have to use the --whole-archive/--no-whole-archive linking option
instead of --start-group/--end-group, otherwise linking may fail because
of unresolved symbols, or the resulting binary will be unusable.

We also need to use the P flag for ar, otherwise final linking may fail.

To squash that nasty warning message and make better use of the newly
gained OF_CONTROL feature, let's convert the calxedagmac driver to the
"new" driver model.
The conversion is pretty straight forward, mostly just adjusting the
use of the involved data structures.
The only actual change is the required split of the receive routine into
a receive and free_pkt part.
Also this allows us to get rid of the hardcoded platform information and
explicit init calls.

This also uses the opportunity to wrap the code decoding the MMIO
register base address, to make it safe for using PHYS_64BIT later.

strn(cat|cpy) has a bad habit of not nul-terminating the destination,
resulting in constructions like

	strncpy(foo, bar, sizeof(foo) - 1);
	foo[sizeof(foo) - 1] = '\0';

However, it is very easy to forget about this behavior and accidentally
leave a string unterminated. This has shown up in some recent coverity
scans [1, 2] (including code recently touched by yours truly).

Fortunately, the guys at OpenBSD came up with strl(cat|cpy), which always
nul-terminate strings. These functions are already in U-Boot, so we should
encourage new code to use them instead of strn(cat|cpy).
