Subject[PATCH v3 00/24] C6X: New architecture
Date
Here is v3 of the C6X architecture patch series. Patches are
available in 'upstream-v3' branch at:

git@linux-c6x.org:/git/projects/linux-c6x-upstreaming

A prebuilt GNU toolchain can be found at:

http://www.codesourcery.com/sgpp/lite/c6000/portal/release1882

The toolchain bits have also been contributed upstream.

This architecture supports members of the Texas Instruments family
of C6x single and multicore DSPs. The multicore DSPs do not support
cache coherancy, so are not suitable for SMP. Also, these are no-mmu
processors. This core architecture is VLIW with an instruction set
optimized for DSP applications (lots of registers, bit manipulation
instructions, fast multiply, no divide). For details see:

http://processors.wiki.ti.com/index.php/Main_Page


Changes from the previous patchset are:

* Added a patch for asm-generic/io.h to fix iounmap decl.

* Removed the soc-64xx.c files and soc probe code. The only
remaining code that makes decisions based on SoC-model is
the clkdev code. That should go away once generic clock
binding is available and clock code makes better use of
devicetree.

* Split out SoC-specific DTSI files from the platform DTS files

* Added device tree binding documentation

* Other device tree cleanups per feedback from Grant

* Cleaned up timer and interrupt code per feedback from tglx

* Created a generalized Device State Config (DSCR) driver with
SoC-specific details moved into the device tree

* Removed obsolete IRQF_DISABLED

* Removed Power State Controller (PSC) code for now. Will
reintroduce it when needed by drivers.

* Add missing iounmap to EMIF driver

* Removed unneeded (by GCC) apply_relocate() from module support

* Removed deprecated sys_mmap

* Fixed race to idle in cpu_idle loop

* Removed superfluous c6x_power_off

* Cleaned up Kconfig/Makefile issues pointed out by Sam

* Use force_sigsegv to avoid SIGSEGV loops

* Added additional comment to generic strnlen_user patch

Mark Salter (24):
fix default __strnlen_user macro
fixed generic page.h for non-zero PAGE_OFFSET
add ELF machine define for TI C6X DSPs
add missing __iomem to generic iounmap declaration
