2011-05-10	MIPS: Octeon: Guard the Kconfig body with CPU_CAVIUM_OCTEON	David Daney
	Instead of making each Octeon specific option depend on CPU_CAVIUM_OCTEON, gate the body of the entire file with CPU_CAVIUM_OCTEON. With this change, CAVIUM_OCTEON_SPECIFIC_OPTIONS becomes useless, so get rid of it as well.

2010-10-29	MIPS: Octeon: Apply CN63XXP1 errata workarounds.	David Daney
	The CN63XXP1 needs a couple of workarounds to ensure memory is not written in unexpected ways. All PREF with hints in the range 0-4,6-24 are replaced with PREF 28. We pass a flag to the assembler to cover compiler generated code, and patch uasm for the dynamically generated code. The write buffer threshold is reduced to 4.

2010-10-29	MIPS: Octeon: Rewrite DMA mapping functions.	David Daney
	All Octeon chips can support more than 4GB of RAM. Also due to how Octeon PCI is setup, even some configurations with less than 4GB of RAM will have portions that are not accessible from 32-bit devices. Enable the swiotlb code to handle the cases where a device cannot directly do DMA. This is a complete rewrite of the Octeon DMA mapping code.

2010-10-04	MIPS: Octeon: Determine if helper needs to be built	Andreas Bießmann
	This patch adds an config switch to determine if we need to build some workaround helper files. The staging driver octeon-ethernet references some symbols which are only built when PCI is enabled. The new config switch enables these symbols in bothe cases.

2009-01-11	MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon.	David Daney
	These are the rest of the new files needed to add OCTEON processor support to the Linux kernel. Other than Makefile and Kconfig which should be obvious, we have: csrc-octeon.c -- Clock source driver for OCTEON. dma-octeon.c -- Helper functions for mapping DMA memory. flash_setup.c -- Register on-board flash with the MTD subsystem. octeon-irq.c -- OCTEON interrupt controller managment. octeon-memcpy.S -- Optimized memcpy() implementation. serial.c -- Register 8250 platform driver and early console. setup.c -- Early architecture initialization. smp.c -- OCTEON SMP support. octeon_switch.S -- Scheduler context switch for OCTEON. c-octeon.c -- OCTEON cache controller support. cex-oct.S -- OCTEON cache exception handler. asm/mach-cavium-octeon/*.h -- Architecture include files.
