2021-01-20ARM: remove u300 platformArnd Bergmann
The Ericsson U300 platform was one of two ARM929 based SoC platforms for mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP into ST-Ericsson, the other one being the ST Nomadik. The platform was not widely adopted in Linux based systems and was replaced with the far superior ST-Ericsson U8500 in 2011, but Linus Walleij kept maintaining the code for the whole time. Linus continues to use the Nomadik machine, but decided to drop u300 from the kernel as part of this year's spring cleaning. Thanks for having maintained it all these years.

2021-01-20ARM: remove tango platformArnd Bergmann
The smp8758 (tango4) SoC was the last generation of set-top-box chips to come out of Sigma Designs, and support was added by Marc Gonzalez and Måns Rullgård between 2015 and 2017, before the company went out of business and the products were abandoned. The chip is used in some set-top-boxes such as the Popcorn Hour A-500, which could have seen some adoption by hobbyists. This has not happened in the past four years, and support for the more widely used MIPS based SoCs was never merged at all. Thanks to Marc and Måns for maintaining for the past years even after the death of the platform.

2021-01-20ARM: remove zte zx platformArnd Bergmann
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

2021-01-20ARM: remove sirf prima2/atlas platformsArnd Bergmann
The SiRF Prima2 and Atlas platform code was contributed by Cambridge Silicon Radio (CSR) after aquiring the original SiRF company, and maintained by Barry Song. CSR was subsequently acquired by Qualcomm, who no longer have an interest in maintaining the SoC platform but instead have released more recent SoCs for the same market in the Snapdragon family. As Barry is no longer working for the company, nobody else there wants to maintain it, and there are no third-party users, the best way forward seems to be to completely remove it. Thanks to Barry for maintaining the platform for the past ten years.

2020-12-01kbuild: Hoist '--orphan-handling' into KconfigNathan Chancellor
Currently, '--orphan-handling=warn' is spread out across four different architectures in their respective Makefiles, which makes it a little unruly to deal with in case it needs to be disabled for a specific linker version (in this case, ld.lld 10.0.1). To make it easier to control this, hoist this warning into Kconfig and the main Makefile so that disabling it is simpler, as the warning will only be enabled in a couple places (main Makefile and a couple of compressed boot folders that blow away LDFLAGS_vmlinx) and making it conditional is easier due to Kconfig syntax. One small additional benefit of this is saving a call to ld-option on incremental builds because we will have already evaluated it for CONFIG_LD_ORPHAN_WARN. To keep the list of supported architectures the same, introduce CONFIG_ARCH_WANT_LD_ORPHAN_WARN, which an architecture can select to gain this automatically after all of the sections are specified and size asserted. A special thanks to Kees Cook for the help text on this config.

2020-09-25kbuild: preprocess module linker scriptMasahiro Yamada
There was a request to preprocess the module linker script like we do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512) The difference between vmlinux.lds and module.lds is that the latter is needed for external module builds, thus must be cleaned up by 'make mrproper' instead of 'make clean'. Also, it must be created by 'make modules_prepare'. You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by 'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to arch/$(SRCARCH)/include/asm/module.lds.h, which is included from scripts/module.lds.S. scripts/module.lds is fine because 'make clean' keeps all the build artifacts under scripts/.

2020-02-21ARM: 8961/2: Fix Kbuild issue caused by per-task stack protector GCC pluginArd Biesheuvel
When using plugins, GCC requires that the -fplugin= options precedes any of its plugin arguments appearing on the command line as well. This is usually not a concern, but as it turns out, this requirement is causing some issues with ARM's per-task stack protector plugin and Kbuild's implementation of $(cc-option). When the per-task stack protector plugin is enabled, and we tweak the implementation of cc-option not to pipe the stderr output of GCC to /dev/null, the following output is generated when GCC is executed in the context of cc-option: cc1: error: plugin arm_ssp_per_task_plugin should be specified before \ -fplugin-arg-arm_ssp_per_task_plugin-tso=1 in the command line cc1: error: plugin arm_ssp_per_task_plugin should be specified before \ -fplugin-arg-arm_ssp_per_task_plugin-offset=24 in the command line These errors will cause any option passed to cc-option to be treated as unsupported, which is obviously incorrect. The cause of this issue is the fact that the -fplugin= argument is added to GCC_PLUGINS_CFLAGS, whereas the arguments above are added to KBUILD_CFLAGS, and the contents of the former get filtered out of the latter before being passed to the GCC running the cc-option test, and so the -fplugin= option does not appear at all on the GCC command line. Adding the arguments to GCC_PLUGINS_CFLAGS instead of KBUILD_CFLAGS would be the correct approach here, if it weren't for the fact that we are using $(eval) to defer the moment that they are added until after asm-offsets.h is generated, which is after the point where the contents of GCC_PLUGINS_CFLAGS are added to KBUILD_CFLAGS. So instead, we have to add our plugin arguments to both. For similar reasons, we cannot append DISABLE_ARM_SSP_PER_TASK_PLUGIN to KBUILD_CFLAGS, as it will be passed to GCC when executing in the context of cc-option, whereas the other plugin arguments will have been filtered out, resulting in a similar error and false negative result as above. So add it to ccflags-y instead.

Always build with '-meabi gnu' when using clang but ensure that '-pg' (which is added with CONFIG_FUNCTION_TRACER and its prereq CONFIG_HAVE_FUNCTION_TRACER) cannot be added with it unless this is fixed (which means using clang 10.0.0 and newer).

2019-08-14ARM: remove Intel iop33x and iop13xx supportArnd Bergmann
There are three families of IOP machines we support in Linux: iop32x (which includes EP80219), iop33x and iop13xx (aka IOP34x aka WP8134x). All products we support in the kernel are based on the first of these, iop32x, the other families only ever supported the Intel reference boards but no actual machine anyone could ever buy. While one could clearly make them all three work in a single kernel with some work, this takes the easy way out, removing the later two platforms entirely, under the assumption that there are no remaining users. Earlier versions of OpenWRT and Debian both had support for iop32x but not the others, and they both dropped iop32x as well in their 2015 releases.

This reverts commit e8c24bbda7d5eba6df5ca45e5462fd3f96b8f217. GCC 4.7, which is still permitted, emits code using the original syntax. This means we end up with lots of assembler warnings when building with a currently-supported version of gcc. Revert the commit (with fixups to keep the follow-on -mauto-it change) to avoid these warnings. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
