Subject: [PATCH v2 00/24] C6X: New architecture patch set
Newsgroups: gmane.linux.kernel
Date: Wednesday 31st August 2011 21:26:35 UTC (over 5 years ago)
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
