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]

iomap: fix 64 bits resources on 32 bits

2008-04-29T15:06:02+00:00

Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.

This fixes all definitions of pci_iomap() to use resource_size_t.  I also
"fixed" the 64bits arch for consistency.

[MIPS] Eleminate local symbols from the symbol table.

2008-01-29T10:14:59+00:00

These symbols appear in oprofile output, stacktraces and similar but only
make the output harder to read.  Many identical symbol names such as
"both_aligned" were also being used in multiple source files making it
impossible to see which file actually was meant.  So let's get rid of them.

[MIPS] IP28: added cache barrier to assembly routines

2008-01-29T10:14:58+00:00

IP28 needs special treatment to avoid speculative accesses. gcc
takes care for .c code, but for assembly code we need to do it
manually.

This is taken from Peter Fuersts IP28 patches.
