[PATCH 00/62] Remove CONFIG_MTD_PARTITIONS

[PATCH 00/62] Remove CONFIG_MTD_PARTITIONS

[Jamie Iles]

This series remove the configuration option CONFIG_MTD_PARTITIONS so that
partitioning support is always enabled in the kernel.  A new set of symbols
for registering MTD devices (mtd_device_register()/mtd_device_unregister())
are introduced that replace add_mtd_device()/add_mtd_partitions() and their
removal counterparts and the preprocessor conditionals in drivers are removed
so that we can always register partitions.

Most of the driver changes are only compile tested but physmap and gpio-nand
have been tested on hardware.

This series is based on next-20110519 so that the new lantiq driver can be
converted.  There are a couple of small conflicts with Artem's tree but are
fairly easily resolved.

[PATCH 01/62] mtd: always build partitioning support

[Jamie Iles]

There are very few situations where MTD partitioning is not required,
and the benefit in code size reduction by making this configurable does
not warrant the level of ifdeffery needed.

[PATCH 02/62] mtd: introduce mtd_device_(un)register()

[Jamie Iles]

To prepare for the removal of add_mtd_device and add_mtd_partitions(),
introduce mtd_device_register().  This will create partitions if they
are supplied or register the whole device if there are no partitions.

Once all drivers are converted to use mtd_device_register(),
add_mtd_device() and add_mtd_partitions() will be made internal only.

[PATCH 03/62] mtd: provide of_mtd_parse_partitions for !CONFIG_MTD_OF_PARTS

[Jamie Iles]

If we don't have OpenFirmware enabled then provide a stub
of_mtd_parse_partitions that returns no partitions so drivers don't need
ifdeffery inside.

[PATCH 59/62] mtd: convert remaining users to mtd_device_register()

[Jamie Iles]

The older add_mtd_device()/add_mtd_partitions() and their removal
counterparts will soon be gone.  Replace uses with mtd_device_register()
and mtd_device_unregister().

[PATCH 60/62] mtd/lantiq: convert to mtd_device_register()

[Jamie Iles]

Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS
preprocessor conditionals as partitioning is always available.

[PATCH 61/62] mtd: remove add_mtd_partitions, add_mtd_device and friends

[Jamie Iles]

These symbols are replaced with mtd_device_register() (and removal with
mtd_device_unregister()) for public registration.

It does make sense to describe the function in the "interface" file, but
in the kernel we add the kernel-doc comments above the function
implementation, this is just the established practice. You may find some
examples where the description is in the .h file, but this is rare (yes,
the kernel is fare from being consistent).

So please, move the descriptive comments to mtdcore.c.

Also, please, check the kernel-doc comments buy feeding your file to
scripts kernel-doc and make sure it does not generate errors or
warnings. 

Please, do not re-send all patches, just this one, if possible. Note, if
something requires a minor conflict resolution - I can do this.

[PATCHv2] mtd: introduce mtd_device_(un)register()

[Jamie Iles]

To prepare for the removal of add_mtd_device and add_mtd_partitions(),
introduce mtd_device_register().  This will create partitions if they
are supplied or register the whole device if there are no partitions.

Once all drivers are converted to use mtd_device_register(),
add_mtd_device() and add_mtd_partitions() will be made internal only.

v2: move kerneldoc to implementation file and fixup some kerneldoc
warnings.

i vaguely recall attempting to submit new functions like this a while
ago, but ultimately it was rejected due to the different behavior mtd
drivers had wrt partitions and whole devices

I think these cases can still be covered - mtd_device_register() can be 
called twice - once with partitions and once without so it's just like 
calling add_mtd_device() then add_mtd_partitions().  The unregistering 
code deletes all registered partitions then only the master if it has 
been registered.

I don't believe these patches should have changed the behaviour of any 
of the drivers (other than it's now not possible to select whether the 
device is partitioned or not by a Kconfig option), but that can be done 
at runtime through command line partitioning perhaps.

Pushed the whole series to l2-mtd-2.6.git tree.
