Commit a0f97e06a4 ("kbuild: enable 'make CFLAGS=...' to add
additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.
Commit 222d394d30 ("kbuild: enable 'make AFLAGS=...' to add
additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.
Commit 06c5040cdb ("kbuild: enable 'make CPPFLAGS=...' to add
additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.
For some reason, LDFLAGS was not renamed.
Using a well-known variable like LDFLAGS may result in accidental
override of the variable.
Kbuild generally uses KBUILD_ prefixed variables for the internally
appended options, so here is one more conversion to sanitize the
naming convention.
I did not touch Makefiles under tools/ since the tools build system
is a different world.

at least MIPS should agree on the function return type.

As Documentation/kbuild/makefile.txt says, it is a typical mistake
to forget the FORCE prerequisite for the rule invoked by if_changed.
Add the FORCE to the prerequisite, but it must be filtered-out from
the files passed to the 'cat' command. Because this rule generates
.vmlinux.its.S.cmd, vmlinux.its.S must be specified as targets so
that the .cmd file is included.

This reverts commit 0f9da844d8.
It is true that commit 0f9da844d8 ("MIPS: boot: Define __ASSEMBLY__
for its.S build") fixed the build error, but it should not have
defined __ASSEMBLY__ just for textual substitution in arbitrary data.
The file is image tree source in this case, but the purpose of using
CPP is to replace some macros.
I merged a better solution, commit a95b37e20d ("kbuild: get
<linux/compiler_types.h> out of <linux/kconfig.h>"). The original
fix-up is no longer needed.

The debug definitions were missing for MACH_JZ4770, resulting in a build
failure when DEBUG_ZBOOT was set.
Since the UART addresses are the same across all Ingenic SoCs, we just
use a #ifdef CONFIG_MACH_INGENIC instead of checking for individual
Ingenic SoCs.
Additionally, I added a #define for the UART0 address in-code and
dropped the <asm/mach-jz4740/base.h> include, for the reason that this
include file is slowly being phased out as the whole platform is being
moved to devicetree.

In preparation for removing some of the MIPS compiler intrinsics from
arch/mips/lib, first update the build of vmlinuz to use the generic
ashldi3 from lib.
Both ashldi3 and bswapsi objects need to be built with different CFLAGS
for inclusion to vmlinuz rather than simply including the object built
for the main kernel image. The objects cannot be built directly from
source, since CONFIG_MODVERSIONS changes cmd_cc_o_c to prevent this.
Split the rule to ship ashldi3 and bswapsi from the relevant source
locations.
These files make no reference to other files in their directory, so the
additional CFLAGS are apparently unnecessary - remove them as well.

The MIPS %.its.S compiler command did not define __ASSEMBLY__, which meant
when compiler_types.h was added to kconfig.h, unexpected things appeared
(e.g. struct declarations) which should not have been present. As done in
the general %.S compiler command, __ASSEMBLY__ is now included here too.

Improve the DTS files by removing all the leading "0x" and zeros to fix
the following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +
For simplicity, two sed expressions were used to solve each warnings
separately.
To make the regex expression more robust a few other issues were
resolved, namely setting unit-address to lower case, and adding a
whitespace before the the opening curly brace:

If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.
Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.
One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.
Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled. All clutter things in Makefiles go away.
As a bonus clean-up, I also removed dts-dirs. Just use subdir-y
directly to traverse sub-directories.
