s/attibute/attribute/ and s/previosly/previously/ in comments.

fix various typos in word `interrupt', mainly in comments.

Fix workaround for SH-3 PCMCIA bug in accordance with description
found in TECH I vol. 14 (CQ Publishing, Tokyo, 2002, in Japanese),
as well as experiment on real hardware:

Byte-access to area 6 becomes word-access (both CE1# and CE2# are
wrongly asserted), if preceding access is word-wise. Inserting a
dummy byte-access works around the problem. Area 5 is not affected.

Therefore,

(1) Insert a dummy byte-read before all byte-wise operations.

(2) Restrict the workaround to area 6 (channel 0), and rename
fixup_sh3_pcmcia_area() to fixup_sh3_pcmcia_area6() for clarity.

Also, we used to use 0xba000000 (== HD64461_PCC0_IOBASE) as target
for the dummy read. However, this can modify device states, which
breaks ep(4) at least. Thus,

(3) Use HD64461_PCC0_MEMBASE as target for the dummy read. This is
assigned to attribute memory space, and byte-read should be
harmless.

enable to power off and reset card.

cosmetic changes. (whitespace,<tab>)

When we attach a channel, set a high level to DRV control pin of the
external buffer for the PC card connected to the channel. This hack
makes pcmcia cards "being used" at the boot time (by WinCE or NetBSD)
correctly detected. A machine running with root on NFS can now be
properly rebooted.

Add option HD64461PCMCIA_REORDER_ATTACH that attaches channels in
reversed order.

When you boot with two CF cards inserted, this options makes the one
in the "memory only" slot (channel 1), which is almost always the card
with the NetBSD install, attached as wd0.

Unlike using fixed unit numbers in the kernel config, if you boot with
only a single CF card, that single card will still be wd0 regardless
of which slot it is inserted in.

http://mail-index.netbsd.org/port-hpcsh/2003/10/23/0000.html provides
a more verbose description of why this option is convenient for most
usage patterns.

In hd64461pcmcia_chip_io_map set *windowp to 0.

This driver ignores i/o window handle, but most 'at pcmcia'
attachments init their sc_io_window to -1 and then check at detach
time if it was changed from the "bad" value. Keep them happy, so that
they can correctly clean up when card is detached.

This merge changes the device switch tables from static array to

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Use CONFIG_HOOK_BRIGHTNESS* to support WSDISPLAYIO_PARAM_BRIGHTNESS.
Use CONFIG_HOOK_POWERCONTROL_LCDLIGHT to turn on/off the LCD in
response to WSDISPLAYIO_SVIDEO.

Implementation of these hooks for Jornada 680 is to follow shortly.

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

Implement trivial WSDISPLAYIO_SVIDEO that flips DON bit in LCDLDR1.
This only turns off the display in the LCD controller.

TODO: Need to add a platform specific way to turn the screen on and
off as well (e.g. on Jornada 680 this is bit 0 in hd64461 GPIO port B).

In hd64461video_update_videochip_status init depth to supress bogus
-Wuninitialized.

Move the definition of enum hd64461video_display_mode out of the
definition of struct hd64461video_chip. Makes gcc3 happy.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

You must set 'HPCFB_SWAP_*' if bytes are stored in reverse order, i.e.
little endian like order, however, usage of 'HPCFB_SWAP_*' was widely
misunderstood because it reminded you of 'RI_BSWAP' in raster operation.
Please note that 'RI_BSWAP' indicate that frame buffer byte order is different
from natural order of system while 'HPCFB_REVORDER_*' is independent of
system byte order.
