Jamie Iles a17f7ca510 mtd: cs553x_nand: convert to mtd_device_register()
Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS
preprocessor conditionals as partitioning is always available.

Mart Raudsepp 641f43669f [MTD] [NAND] cs553x_nand: command line partitioning support
Implements kernel command line partitioning support for the CS5535/CS5536 chipsets driver.

For that the following is done:

* cs553x_cleanup(): try the cleanup for all chip selects to not leak memory
* Assign a unique name for each chip select to be separately addressable in the command line mtd-id portion(s)
* Use the already defined PIN_OPT_IDE constant where appropriate for readability
* Include command line partitioning support when CONFIG_MTD_PARTS is set

Jean Delvare 6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

The previous change of the command / hardware control allows to
remove the write_byte/word functions completely, as their only
user were nand_command and nand_command_lp.

Thomas Gleixner 7abd3ef987 [MTD] Refactor NAND hwcontrol to cmd_ctrl
The hwcontrol function enforced a step by step state machine
for any kind of hardware chip access. Let the hardware driver
know which control bits are set and inform it about a change
of the control lines. Let the hardware driver write out the
command and address bytes directly. This gives a peformance
advantage for address bus controlled chips and simplifies the
quirks in the hardware drivers.

David Woodhouse 552d920518 [MTD] Fix module refcounting in NAND board drivers.
The _board_ driver needs to be mtd->owner, and it in turn pins the
nand.ko module. Fix them all to actually do that, and fix nand.ko not to
overwrite it -- and also to check that the caller sets it, if the caller
is a module.
