MIPS: Octeon: Rewrite interrupt handling code.

2011-03-29T12:48:06+00:00

This includes conversion to new style irq_chip functions, and
correctly enabling/disabling per-CPU interrupts.

The hardware interrupt bit to irq number mapping is now done with a
flexible map, instead of by bit twiddling the irq number.

[ tglx: Adjusted to new irq_cpu_on/offline callbacks and
        __irq_set_affinity_lock ]

MIPS: Octeon: Add register definitions for EHCI / OHCI USB glue logic.

2010-10-29T18:08:43+00:00

The EHCI and OHCI blocks connection to the I/O bus is controlled by
these registers.

MIPS: Octeon: Add octeon_get_io_clock_rate() for cn63xx

2010-10-29T18:08:40+00:00

Starting with cn63xx Octeon I/O blocks are clocked at a different rate
than the CPU.  Add a new function octeon_get_io_clock_rate() that
yields the I/O clock rate.

Also rearrange octeon_get_clock_rate() to get the value from the saved
sysinfo structure.

MIPS: Octeon: Update L2 Cache code for CN63XX

2010-10-29T18:08:35+00:00

The CN63XX has a different L2 cache architecture.  Update the helper
functions to reflect this.

Some joining of split lines was also done to improve readability, as
well as reformatting of comments.

MIPS: Octeon: Update register definitions for CN63XX chips

2010-10-29T18:08:33+00:00

The CN63XX is a new 6-CPU SOC based on the new OCTEON II CPU cores.

Join some lines back together.  This makes some of them exceed 80
columns, but they are uninteresting and this unclutters things.

MIPS: Octeon: Rewrite DMA mapping functions.

2010-10-29T18:08:32+00:00

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.

MIPS: Octeon: Allow more than 3.75GB of memory with PCIe

2010-08-05T12:26:31+00:00

We reserve the 3.75GB - 4GB region of PCIe address space for device to
device transfers, making the corresponding physical memory under
direct mapping unavailable for DMA.

To allow for PCIe DMA to all physical memory we map this chunk of
physical memory with BAR1.  Because of the resulting discontinuity in
the mapping function, we remove a page of memory at each end of the
range so multi-page DMA buffers can never be allocated that span the
range.

MIPS: Octeon: Implement delays with cycle counter.

2010-08-05T12:26:20+00:00

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.
