Maxim Levitsky 0ab30494bc memstick: add support for legacy memorysticks
Based partially on MS standard spec quotes from Alex Dubov.

As any code that works with user data this driver isn't recommended to use
to write cards that contain valuable data.

It tries its best though to avoid data corruption and possible damage to
the card.

Tested on MS DUO 64 MB card on Ricoh R592 card reader.

config MEMSTICK_UNSAFE_RESUME
bool "Allow unsafe resume (DANGEROUS)"
help
If you say Y here, the MemoryStick layer will assume that all
cards stayed in their respective slots during the suspend. The
normal behaviour is to remove them at suspend and
redetecting them at resume. Breaking this assumption will
in most cases result in data corruption.
This option is usually just for embedded systems which use
a MemoryStick card for rootfs. Most people should say N here.
config MSPRO_BLOCK
tristate "MemoryStick Pro block device driver"
depends on BLOCK
help
Say Y here to enable the MemoryStick Pro block device driver
support. This provides a block device driver, which you can use
to mount the filesystem. Almost everyone wishing MemoryStick
support should say Y or M here.
config MS_BLOCK
tristate "MemoryStick Standard device driver"
depends on BLOCK
help
Say Y here to enable the MemoryStick Standard device driver
support. This provides a block device driver, which you can use
to mount the filesystem.
This driver works with old (bulky) MemoryStick and MemoryStick Duo
but not PRO. Say Y if you have such card.
Driver is new and not yet well tested, thus it can damage your card
(even permanently)
