MIPS: Octeon: Implement delays with cycle counter.
...
Power throttling make deterministic delay loops impossible.
Re-implement delays using the cycle counter. This also allows us to
get rid of the code that calculates loops per jiffy.

MIPS: Octeon: HOTPLUG_CPU fixes.
...
* Rename camel-case InitTLBStart_addr to octeon_bootloader_entry_addr.
* Convert calls to cvmx_read64_uint32(), to simple pointer
dereferences.
* Set proper ebase.
* Don't confuse coreid and cpu numbers.
* Try to maintain consistent bootloader coremask.
* Update the signature and boot_init_vector of supported bootloaders.

MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon.
...
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.
