[MIPS] Remove obsolete isa_slot_offset

2008-07-15T17:44:29+00:00

 The isa_slot_offset variable and its __ISA_IO_base macro is not used
anywhere anymore.  It does not look like a decent interface per today's
standards either.  Remove both including all places of initialization.

[MIPS] Allow setting of the cache attribute at run time.

2008-04-28T16:14:25+00:00

Slightly tacky, but there is a precedent in the sparc archirecture code.

Remove dma_cache_(wback|inv|wback_inv) functions

2007-10-17T15:42:57+00:00

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes.  Originally it was basically the raw
MIPS low level cache API exported to the entire world.  The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync.  So
remove it rsp.  turn the surviving bits back into an arch private API, as
discussed on linux-arch.

[MIPS] Workaround for a sparse warning in include/asm-mips/io.h

2007-07-12T16:41:10+00:00

CKSEG1ADDR() returns unsigned int value on 32bit kernel.  Cast it to
unsigned long to get rid of this warning:

include2/asm/io.h:215:12: warning: cast adds address space to expression ()

[MIPS] Make ioremap() work on TX39/49 special unmapped segment

2007-07-10T16:33:03+00:00

TX39XX and TX49XX have "reserved" segment in CKSEG3 area.
0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on TX39XX
are reserved (unmapped, uncached).  Controllers on these SoCs are
placed in this segment.

This patch add plat_ioremap() and plat_iounmap() to override default
behavior and implement these hooks for TX39/TX49.

[MIPS] Iomap implementation.

2007-02-18T21:31:34+00:00

This implementation has support for the concept of one separate ioport
address space by PCI domain.  A pointer to the virtual address where
the port space of a domain has been mapped has been added to struct
pci_controller and systems should be fixed to fill in this value. For
single domain systems this will be the same value as passed to
set_io_port_base().

[PATCH] kill eth_io_copy_and_sum()

2007-02-09T17:14:07+00:00

On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source.  For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

[MIPS] FLATMEM: introduce PHYS_OFFSET.

2007-02-06T16:53:13+00:00

The old code was assuming that min_low_pfn was always 0. This
means that platforms having a big hole at their memory start
paid the price of wasting some memory for the allocation of
unused entries in mem_map[].

This patch prevents this waste.

It introduces PHYS_OFFSET define which is the start of the
physical memory and uses it wherever needed. Specially when
converting physical/virtual addresses into virtual/physical
ones.

Currently all platforms defines PHYS_OFFSET to 0.
