This was introduced more than 3 years ago, and since then only generic janitorial changes were made without further addition of actual support for "real" devices. This is therefore a cost with no benefits to keep in the tree. If someone wishes to revive this code, it is always possible to retrieve it from the Git repository.

Commit bcae8aeb32 "[ARM] S3C24A0: Initial architecture support files" brought in a bunch of files while explicitly leaving out the corresponding Kconfig entry, stating that the series is not complete. More than 2.5 years later, the support for this has not seen any progress. This is therefore dead code.

2011-07-09ARM: CSR: Adding CSR SiRFprimaII board supportBinghua Duan
SiRFprimaII is the latest generation application processor from CSR’s Multifunction SoC product family. Designed around an ARM cortex A9 core, high-speed memory bus, advanced 3D accelerator and full-HD multi-format video decoder, SiRFprimaII is able to meet the needs of complicated applications for modern multifunction devices that require heavy concurrent applications and fluid user experience. Integrated with GPS baseband, analog and PMU, this new platform is designed to provide a cost effective solution for Automotive and Consumer markets. This patch adds the basic support for this SoC and EVB board based on device tree. It is following the ZYNQ of Xilinx in some degree.

2011-06-20ARM: Xilinx: Adding Xilinx board supportJohn Linn
The 1st board support is minimal to get a system up and running on the Xilinx platform. This platform reuses the clock implementation from plat-versatile, and it depends entirely on CONFIG_OF support. There is only one board support file which obtains all device information from a device tree dtb file which is passed to the kernel at boot time. Signed-off-by: John Linn <john.linn@xilinx.com>

2011-05-02ARM: mach-stmp378x: remove machWolfram Sang
This mach has not seen any updates since the initial inclusion besides generic cleanup. Furthermore: - The i.MX23 covered in mach-mxs is just a renamed version of the STMP378x. - mach-stmp378x has a lot of reinvented interfaces, leaking all sorts of mach-related includes into the drivers. One example is the dmaengine which does not use the linux dmaengine-API but some privately exported symbols. So drivers cannot be reused. mach-mxs does it better. - There is only one board defined (which I couldn't find any trace of despite being a development board). It has been converted to mach-mxs in a previous patch. Since the only user of this mach was converted, it means that mach-stmp378x can go.

This mach has not seen any updates since the initial inclusion besides generic cleanup. Furthermore: - It has a lot of reinvented interfaces, leaking all sorts of mach-related includes into the drivers. One example is the dmaengine which does not use the linux dmaengine-API but some privately exported symbols. So, drivers cannot be reused. mach-mxs is very similar and does it better. - It can be doubted that this worked at all. Check the DMA routines in stmp37xx.c for copy/paste bugs. A lot of APBX-related stuff is actually writing into registers for APBH. - There is only one board defined (which I couldn't find any trace of despite being a development board). In this board, only two devices have resources, the debug uart and the application uart. Neither of those have the needed custom drivers merged (and never will). debug uart is amba-pl011 which has an in-kernel driver without the mach-specific-stuff. appuart has a driver which was introduced for mach-mxs, and this one is reusable for a properly done mach. So, this single board registers only unsupported devices and the generic code looks suspicious and has poor design. Delete this stuff. If there is interest, it is wiser to restart using mach-mxs.

2011-03-10ARM: 6781/1: Thumb-2: Work around buggy Thumb-2 short branch relocations in gasDave Martin
Various binutils versions can resolve Thumb-2 branches to locally-defined, preemptible global symbols as short-range "b.n" branch instructions. This is a problem, because there's no guarantee the final destination of the symbol, or any candidate locations for a trampoline, are within range of the branch. For this reason, the kernel does not support fixing up the R_ARM_THM_JUMP11 (102) relocation in modules at all, and it makes little sense to add support. The symptom is that the kernel fails with an "unsupported relocation" error when loading some modules. Until fixed tools are available, passing -fno-optimize-sibling-calls to gcc should prevent gcc generating code which hits this problem, at the cost of a bit of extra runtime stack usage in some cases. The problem is described in more detail at: https://bugs.launchpad.net/binutils-linaro/+bug/725126 Only Thumb-2 kernels are affected. This patch adds a new CONFIG_THUMB2_AVOID_R_ARM_THM_JUMP11 config option which adds -fno-optimize-sibling-calls to CFLAGS_MODULE when building a Thumb-2 kernel.

2011-02-23ARM: add 'uinstall' target for installing uboot kernelsRussell King
We have 'install' and 'zinstall' for installing Image and zImage kernels, so add 'uinstall' to complete the set. This allows developers to have a ~/bin/installkernel script which (eg) copies the kernel to the tftp server automatically once the kernel has built, resulting in a better workflow.

2011-02-21ARM: 6740/1: Place correctly notes section in the linker scriptPawel Moll
Commit 18991197b4b588255ccabf472ebc84db7b66a19c added --build-id linker option when toolchain supports it. ARM one does, but for some reason places the section at 0 when linker script doesn't mention it explicitly. The 1e621a8e3752367d4aae78a8ab00a18fb2793f34 worked around the problem removing this section from binary image with explicit objcopy options, but it still exists in vmlinux, confusing tools like debuggers and perf. This problem was discussed here: http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html http://lists.infradead.org/pipermail/linux-arm-kernel/2010-May/015994.html but the proposed changes to the linker script were substantial. This patch simply places NOTES (36 bytes long, at least when compiled with CodeSourcery toolchain) between data and bss, which seem to be the right place (and suggested by the sample linker script in include/asm-generic/vmlinux.lds.h). It is enough to place it correctly in vmlinux (so debuggers are happy): Section Headers: [11] .data PROGBITS c07ce000 7ce000 020fc0 00 WA 0 0 32 [12] .notes NOTE c07eefc0 7eefc0 000024 00 AX 0 0 4 [13] .bss NOBITS c07ef000 7eefe4 01e628 00 WA 0 0 32 Program Headers: LOAD 0x008000 0xc0008000 0xc0008000 0x7e6fe4 0x805628 RWE 0x8000 NOTE 0x7eefc0 0xc07eefc0 0xc07eefc0 0x00024 0x00024 R E 0x4 Section to Segment mapping: Segment Sections... 00 <...> .data .notes .bss 01 .notes and to get it exposed as /sys/kernel/notes used by perf tools.

2011-02-02ARM: v6k: introduce CPU_V6K optionRussell King
Introduce a CPU_V6K configuration option for platforms to select if they have a V6K CPU core. This allows us to identify whether we need to support ARMv6 CPUs without the V6K SMP extensions at build time. Currently CPU_V6K is just an alias for CPU_V6, and all places which reference CPU_V6 are replaced by (CPU_V6 || CPU_V6K). Select CPU_V6K from platforms which are known to be V6K-only.

Included are basic machine initialization files, register and interrupt definitions, support for the on-chip interrupt controller, high-precision OS timer, GPIO lines, necessary macros for early debug, pulse-width-modulated outputs control, as well as platform device configurations for the specific drivers implemented elsewhere.
