This is an optimised implementation of early printk() for the DECstation.
After the recent conversion to a MIPS-specific generic routine using a
character-by-character output the performance dropped significantly.
This change reverts to the previous speed -- even at 9600 bps of the
serial console the difference is visible with a naked eye; I presume for a
framebuffer it is even worse (it may depend on exactly which one is used
though).
Additionally the change includes a fix for a problem that the old
implementation had -- the format used would not actually limit the length
of the string output. This new implementation uses a local buffer to deal
with it -- even with this additional copying it is much faster than the
generic function.
Plus this driver is registered much earlier than the generic one,
allowing one to see critical messages, such as one about an incorrect CPU
setting used, that are produced beforehand. :-)

There are no I/O ports on the DECstation whatsoever in any configuration
as neither the CPU nor the peripheral buses used have a concept of such.

The current implementation of __pa() for 64-bits kernels with 32-bits
symbols is broken. In this configuration, we need 2 values for
PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space.
When the value in CKSEG0 space is used, it doesn't take into account
of PHYS_OFFSET. Even worse we can't redefine this value.
The patch restores CPHYSADDR() but in __pa()'s implementation because
it removes the need of 2 PAGE_OFFSET.
OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So
this patch assumes there's no need to deal with such kernel in 64-bits
world.

For platforms that use PHYS_OFFSET and do not use a mapped kernel,
this patch automatically adds PHYS_OFFSET into PAGE_OFFSET.
Therefore there are no more needs for them to redefine PAGE_OFFSET.
For mapped kernel, they need to redefine PAGE_OFFSET anyways.

PAGE_OFFSET definition is now using CAC_BASE by default.
This patch also reorder some macros to make them appear
in the same order for both 32 and 64 bits configs.
It also makes use of const.h generic header file to
annotate constants.

Before this patch, when a platform needed to customize one constant in
spaces.h, they need to redefine all of them.
Now they can just redefine one constant and include the generic file
header at the end:
#include <asm/mach-generic/spaces.h>
This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE
for 32 bits platforms because there's no need to do so.
This will avoid some macro duplications. It's important specially if
we'll add complex macros.

No point in adding yet another #ifdef for Loongson since all this mask is

This patch adds support for the generic GPIO API to Au1x00 boards. It requires

Add rudimentary check for the case that the page table overflows due to
merging of s/g elements by the IOMMU. This would have lead to
overwriting of arbitrary memory.
After this change I expect that an offending command will be
unsuccessfully retried until the scsi_device is taken offline by SCSI
core. It's a border case and not worth to implement a recovery
strategy.

Use a speed probe to determine the speed over 1394b buses and of nodes
which report a link speed less than their PHY speed.
Log the effective maximum speed of newly created nodes in dmesg.
Also, read the config ROM (except bus info block) at the maximum speed
rather than S100. This isn't a real optimization though because we
still only use quadlet read requests for the entire ROM.
The patch also adds support for S1600 and S3200, although such hardware
does not exist yet.

Based on patch "the scheduled removal of RAW1394_REQ_ISO_{SEND,LISTEN}"
from Adrian Bunk, November 20 2006.
This patch also removes the underlying facilities in ohci1394 and
disables them in pcilynx. That is, hpsb_host_driver.devctl() and
hpsb_host_driver.transmit_packet() are no longer used for iso reception
and transmission.
Since video1394 and dv1394 only work with ohci1394 and raw1394's rawiso
interface has never been implemented in pcilynx, pcilynx is now no
longer useful for isochronous applications.
raw1394 will still handle the request types but will complete the
requests with errors that indicate API version conflicts.
