0ea6e61122 Documentation: update broken web addresses.
Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.

dd14be4c27 i2c-ocores: Can add I2C devices to the bus
There is sometimes a need for the ocores driver to add devices to the
bus when installed.

i2c_register_board_info can not always be used, because the I2C devices
 are not known at an early state, they could for instance be connected
 on a I2C bus on a PCI device which has the Open Cores IP.

i2c_new_device can not be used in all cases either since the resulting
bus nummer might be unknown.

The solution is the pass a list of I2C devices in the platform data to
the Open Cores driver. This is useful for MFD drivers.

Besides removing the wrong SB700 device ID, add SB800 support to kernel, by

PCI_DEVICE_ID_ATI_SBX00_SMBUS.

7edcb9abb5 i2c-i801: Use the internal 32-byte buffer on ICH4+
Add an ability to utilize the internal SRAM buffer on ICH4
and newer host controllers to speed up execution of block operations.

I've split the code so that it is more clear which block transaction is
performed.

First of all the host controller's type is identified. isich4 is set when
we think that the controller has the internal buffer. Then, before every
block transaction, if isich4 is set, we attempt to enable the E32B bit in
SMBAUXCTL register.

ad04d5c387 i2c: Cleanups to the i2c-nforce2 bus driver
Summary of changes:

- fixes:
   o legacy I/O region size is 64 bytes, not 8 bytes
- general cleanup:
   o removed code for the unsupported I2C block data, block data,
      proc call and block proc call transfer modes
   o removed detail warnings about unsupported modes that are
     covered in a general warning (unsupported transaction...)
     anyway
   o removed necessity of a definition of struct i2c_adapter
   o moved definition of struct i2c_algorithm, making forward
     declarations of nforce2_access and nforce2_func unnecessary
- minor changes:
   o in the description mention the nForce 5xx chipsets
   o changes my e-mail address in MODULE_AUTHOR

Theses cleanups shrink the driver binary size from 4.0 kB to 2.7 kB
on i386.

54aaa1ca10 [PATCH] I2C: i2c-piix4: Remove the fix_hstcfg parameter
This patch removes the fix_hstcfg option from the driver and related
SMBus Interrupt Select register magic because now we know what are
valid values for this register. This patch updates the documentation
and adds new IRQ mode check so we are sure not to miss any new
"unusual" value.

The PCI quirk for users of fix_hstcfg was not developed because the
chipset lacks of subsystem ID registers and DMI is stated "To be
filled". Impact to existing systems is minimal because the problem
showed up on motherboards like 10 years back. On the other hand users
of newer Serverworks and HT1000 systems won't be misleaded by the
message suggesting to try the fix_hstcfg any more.

e97b81ddbb [PATCH] i2c-parport: Make type parameter mandatory
This patch forces the user to specify what type of adapter is present when
loading i2c-parport or i2c-parport-light.  If none is specified, the driver
init simply fails - instead of assuming adapter type 0.

This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).

Kconfig and documentation updated accordingly.
