Sascha Hauer 6cbefbdcec mtd: tests: nandbiterrs: Fix read_page return value
The number of corrected bitflips is not correctly reported by
the test until the bitflip threshold is reached.

read_page() shall return the number of corrected bitflips, but
mtd_read() returns 0 or a negative error, so we can't forward
its return value. In the absence of an error we always have
calculate the number of bitflips ourselves.

Boris Brezillon d4092d76a4 mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

Iwo Mergler 97b671315e mtd: nandbiterrs: Support for NAND biterrors test on platforms without raw write
Support for NAND biterrors test on platforms without raw write

While the default test mode relies on raw write (mtd_write_oob) to introduce
bit errors into a page, the rewrite test mode doesn't need it.

Changed the overwrite test to use normal writes. The default test mode
is unaffected and still requires raw write as before.

Richard Weinberger 2a6a28e792 mtd: Make MTD tests cancelable
I always go nuts when I start an MTD test on a slow device and have to
wait forever until it finishes. From the debug output I already know
what the issue is but I have to wait or reset the board hard. Resetting
is often not an option (remote access, you don't want lose the current
state, etc...).

The solution is easy, check for pending signals at key positions in the
code. Using that one can even stop a test by pressing CTRL-C as
insmod/modprobe have SIGINT pending.

Brian Norris 1001ff7a4f mtd: tests: fix integer overflow issues
These multiplications are done with 32-bit arithmetic, then converted to
64-bit. We should widen the integers first to prevent overflow. This
could be a problem for large (>4GB) MTD's.

Detected by Coverity.

Huang Shijie 818b973929 mtd: nand: add a helper to detect the nand type
This helper detects that whether the mtd's type is nand type.

Now, it's clear that the MTD_NANDFLASH stands for SLC nand only.
So use the mtd_type_is_nand() to replace the old check method
to do the nand type (include the SLC and MLC) check.

Akinobu Mita 8a9f4aa3ac mtd: tests: incorporate error message for mtdtest_write()
All callers of mtdtest_write() print the same error message on failure.
This incorporates the error message to mtdtest_write() and removes them
from the callers.

Akinobu Mita a995c79228 mtd: tests: rename sources in order to link a helper object
Each mtd test module have a single source whose name is the same as
the module name.  In order to link a single object including helper
functions to every test module, this rename these sources to the
different names.
