MIPS: Outline udelay and fix a few issues.

2009-06-08T15:57:51+00:00

Outlining fixes the issue were on certain CPUs such as the R10000 family
the delay loop would need an extra cycle if it overlaps a cacheline
boundary.

The rewrite also fixes build errors with GCC 4.4 which was changed in
way incompatible with the kernel's inline assembly.

Relying on pure C for computation of the delay value removes the need for
explicit.  The price we pay is a slight slowdown of the computation - to
be fixed on another day.

MIPS: Cavium: Add support for 8k and 32k page sizes.

2009-05-14T12:50:27+00:00

Beyond the requirements of the architecture standard Cavium also supports
8k and 32k pages.

MIPS: IP27: Switch from DMA_IP27 to DMA_COHERENT

2009-01-30T21:32:58+00:00

The special IP27 DMA code selected by DMA_IP27 has been removed a while
ago turning DMA_IP27 into almost a nop.  Also fixup the broken logic of
its last users memcpy.S and memcpy-inatomic.s.

MIPS: Hook up Cavium OCTEON in arch/mips.

2009-01-11T09:57:22+00:00

Take all the OCTEON specific files that were added, and hook them into
the build system for the arch/mips.  For versions of GCC that lack
OCTEON support, override gas target architecture.

MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processors

2008-10-27T16:18:29+00:00

We already have sufficient infrastructure to support VR5500 and VR5500A
series processors.  Here's a Makefile support to make it selectable by
ports, and enable it for NEC EMMA2RH Markeins board.

This patch also fixes a confused target help, and adds 1Gb PageMask bits
supported by VR5500 and its variants.

[MIPS] Fix 64-bit IP checksum code

2008-09-21T12:52:56+00:00

Use unsigned loads to avoid possible misscalculation of IP checksums.  This
bug was instruced in f761106cd728bcf65b7fe161b10221ee00cf7132 (lmo) /
ed99e2bc1dc5dc54eb5a019f4975562dbef20103 (kernel.org).

[Original fix by Atsushi.  Improved instruction scheduling and fix for
unaligned unsigned load by me -- Ralf]
