Here is v2 of the C6X architecture patch series.
Changes from the previous patchset are:
* Replaced 64-by-64 divides (two places) with do_div
* Parse device tree for base address of some miscellaneous SoC registers.
The clkdev code still has a hard-coded address but that will go away when
device tree clock bindings are settled.
* Tweaked the DTS files to more closely match the actual hardware.
* Removed all board-specific files by making better use of device tree.
* Removed CONFIG_NR_IRQS and replaced with hard-coded number which is large
enough for all supported SoCs with room to spare.
* Removed GENERIC_FIND_* references.
* Cleaned up Makefiles and Kconfig files.
* Removed VMLINUX_SYMBOL usage in linker script (not needed for C6X).
* Cleaned up show_cpuinfo.
* Added __HEAD to head.S
* Use generic asm/dma.h
* Added cpu_relax() to busy wait loops in cache code.
* Dropped unneeded module support routines (handled in generic code)
* Cleaned up DMA support.
* Removed deprecated syscalls.
* Removed PTRACE_PEEKUSR and PTRACE_POKEUSR.
* Cleaned up sparse warnings.
This latest patchset is available in the 'upstream-v2' branch of the git repo
