mtd: physmap.c: use mtd_device_parse_register

2011-09-11T12:02:07+00:00

Replace custom invocations of parse_mtd_partitions and mtd_device_register
with common mtd_device_parse_register call. This would bring: standard
handling of all errors, fallback to default partitions, etc.

mtd: drop physmap_configure

2011-09-11T12:01:57+00:00

physmap_configure() and physmap_set_partitions() have no users in kernel.
Out of kernel users should have been converted to regular platform device
long ago. Drop support for this obsolete API.

mtd: physmap: convert to mtd_device_register()

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

ARM: 6910/1: MTD: physmap: let set_vpp() pass a platform_device instead of a map_info

2011-05-20T21:27:34+00:00

The set_vpp() method provided by physmap passes a map_info back to
the platform code, which has little relevance as far as the platform
is concerned (this parameter is completely unused).

Instead, pass the platform_device, which can be used in the pismo
driver to retrieve some important information in a nicer way, instead
of the hack that was in place.

The empty set_vpp function in board-at572d940hf_ek.c is left untouched,
as the board/SoC is scheduled for removal.

ARM: 6904/1: MTD: Add integrator-flash feature to physmap

2011-05-20T21:26:53+00:00

In the process of moving platforms away from integrator-flash
(aka armflash), add to physmap the few features that make
armflash unique:

- optionnal probing for the AFS partition type
- init() and exit() methods, used by Integrator to control
  write access to the various onboard programmable components

mtd: drop CONFIG_MTD_CONCAT ifdefs

2011-03-11T14:22:40+00:00

As MTD_CONCAT is becoming a part of mtd core, it's now meaningless
to to check for it in ifdefs. Drop such references from MTD code.

mtd-physmap: add support users can assign the probe type in board files

2010-08-08T11:28:15+00:00

There are three reasons to add this support:
1. users probably know the interface type of their flashs, then probe
can be faster if they give the right type in platform data since wrong
types will not be detected.
2. sometimes, detecting can cause destory to system. For example, for
kernel XIP, detecting can cause NOR enter a mode instructions can not
be fetched right, which will make kernel crash.
3. For a new probe which is not listed in the rom_probe_types, if users
assign it in board files, physmap can still probe it.

mtd/maps/physmap: catch failure to register MTD_PHYSMAP_COMPAT device

2010-04-20T07:53:52+00:00

If the default Kconfig values are used with MTD_PHYSMAP_COMPAT you end
up with a resource where end < start.  This causes __request_resource to
return a conflict which then returns an -EBUSY error code.  The current
physmap.c code just assumes that the platfom_device_register will always
succeed.

Catch this failure during the physmap_init and propogate the error.
