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.

arch/mips/cavium-octeon/executive and asm/octeon.
These files are used to coordinate resource sharing between all of
the programs running on the OCTEON SOC. The OCTEON processor has many
CPU cores (current parts have up to 16, but more are possible). It
also has a variety of on-chip hardware blocks for things like network
acceleration, encryption and RAID.
One typical configuration is to run Linux on several of the CPU cores,
and other dedicated applications on the other cores.
Resource allocation between the various programs running on the system
(Linux kernel and other dedicated applications) needs to be
coordinated. The code we use to do this we call the 'executive'. All
of this resource allocation and sharing code is gathered together in
the executive directory.
Included in the patch set are the following files:
cvmx-bootmem.c and cvmx-sysinfo.c -- Coordinate memory allocation.
All memory used by the Linux kernel is obtained here at boot time.
cvmx-l2c.c -- Coordinates operations on the shared level 2 cache.
octeon-model.c -- Probes chip capabilities and version.
The corresponding headers are in asm/octeon.
