mtd: remove add_mtd_partitions, add_mtd_device and friends

2011-05-25T01:25:16+00:00

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

mtd: provide of_mtd_parse_partitions for !CONFIG_MTD_OF_PARTS

2011-05-25T01:12:51+00:00

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.

mtd: introduce mtd_device_(un)register()

2011-05-25T01:12:36+00:00

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.

Artem: tweak comments: remove junk tabs, use dots consistently.

mtd: fix master device identification for mtd repartition

2010-12-03T16:32:35+00:00

Function mtd_has_master renamed as mtd_is_partition to follow the function logic.
The patch fixes the problem of checking the right mtd device for partition creation.
To delete partition checking is not needed here so as it is done in mtd_del_partition.
By master we consider the mtd device which does not belong to any partition.

mtd: prepare partition add and del functions for ioctl requests

2010-10-24T23:47:37+00:00

mtd_is_master, mtd_add_partition and mtd_del_partition functions
are added to give the possibility of partition manipulation
by ioctl request.

The old partition add function is modified to fit the dynamic
allocation.

mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUT

2010-10-24T22:37:24+00:00

struct nand_ecclayout is too small for many new chips; OOB regions can be as
large as 448 bytes and may increase more in the future. Thus, copying that
struct to user-space with the ECCGETLAYOUT ioctl is not a good idea; the ioctl
would have to be updated every time there's a change to the current largest
size.

Instead, the old nand_ecclayout is renamed to nand_ecclayout_user and a
new struct nand_ecclayout is created that can accomodate larger sizes and
expand without affecting the user-space. struct nand_ecclayout can still
be used in board drivers without modification -- at least for now.

A new function is provided to convert from the new to the old in order to
allow the deprecated ioctl to continue to work with truncated data. Perhaps
the ioctl, the conversion process, and the struct nand_ecclayout_user can be
removed altogether in the future.

Note: There are comments in nand/davinci_nand.c::nand_davinci_probe()
regarding this issue; this driver (and maybe others) can be updated to
account for extra space. All kernel drivers can use the expanded
nand_ecclayout as a drop-in replacement and ignore its benefits.

mtd: let include/linux/mtd/partitions.h stand on its own

2009-08-03T13:00:14+00:00

When declaring static MTD partitions in board specific code, only
including  should suffice without
gcc nagging us with:

[MTD] Remove option for add_mtd_partitions() to not register partitions.

2009-05-26T15:45:44+00:00

This breaks the dilnetpc map driver, but it could be fixed not to use
that option. We want to simplify the partition handling, and this is a
step towards that.

Remove superfluous 'index' field from private struct mtd_part too, while
we're at it.

[MTD] partitioning utility predicates

2009-03-20T13:16:44+00:00

Move mtd_has_partitions() and mtd_has_cmdlinepart() inlines from a
DaVinci-specific driver to the  header.

Use those to eliminate #ifdefs in two drivers which had their own
definitions of mtd_has_partitions().

Quite a lot of other MTD drivers could benefit from using use one or both
of these to remove #ifdeffery.  Maybe some Janitors would like to help.
