* [MTD NAND] Modify check for modules registering NAND devices without ->ownerDavid Woodhouse2006-05-14
| | | | | | | | Make it work even with compilers which lack the wit to notice that THIS_MODULE is always non-NULL. Use #ifdef MODULE instead. It's only a temporary debugging check anyway. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] Remove gratuitous inclusion of ARM-only header from physmap.cDavid Woodhouse2006-05-14
| | | | | | | | | The physmap platform driver conversion added to physmap.c an include of asm/mach/flash.h which is 1) ARM-specific; and 2) isn't actually necessary. Remove it. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [MTD] Deal correctly with NOR chips which are smaller than the map windowDavid Woodhouse2006-05-13
| | | | | | | | | | | | We used to calculate the number of chips to be zero, allocate an array of that size, then nasty things would happen when we attempt to access the first object in that zero-sized array. Now, if the number of _full_ chips that would fit into the map is zero, we allocate an array of one anyway, and then artificially reduce the total size of the resulting MTD device to fit in the map.

* mtd: fix memory leak in block2mtd_setup()Jesper Juhl2006-05-13
| | | | | | | | | | | | | There's a mem leak in drivers/mtd/devices/block2mtd.c::block2mtd_setup() We can leak 'name' allocated with kmalloc in 'parse_name' if leave via the 'parse_err' macro since it contains a return but doesn't do any freeing. Spotted by coverity checker as bug 615. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* [MTD] Fix module refcounting in NAND board drivers.David Woodhouse2006-05-13
| | | | | | | | | The _board_ driver needs to be mtd->owner, and it in turn pins the nand.ko module. Fix them all to actually do that, and fix nand.ko not to overwrite it -- and also to check that the caller sets it, if the caller is a module. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* mtd: fix memory leaks in phram_setupJesper Juhl2006-05-13
| | | | | | | | | | | | | | There are two code paths in drivers/mtd/devices/phram.c::phram_setup() that will leak memory. Memory is allocated to the variable 'name' with kmalloc() by the parse_name() function, but if we leave by way of the parse_err() macro, then that memory is never kfree()'d, nor is it ever used with register_device() so it won't be freed later either - leak. Found by the Coverity checker as #593 - simple fix below. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | | | | | | | | | | | | Oops. Stupid StudlyCaps. Again. This driver is doubly-deprecated because is was subsumed into doc2000.c and _also_ we want people to start using the new NAND wrapper for these devices anyway.

* [MTD] Convert physmap to platform driverLennert Buytenhek2006-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | After dwmw2 let me know it ought to be done, I rewrote the physmap map driver to be a platform driver. I know zilch about the driver model, so I probably botched it in some way, but I've done some tests on an ixp23xx board which uses physmap, and it all seems to work. In order to not break existing physmap users, I've added some compat code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN is defined and != 0. Also, I've changed the default value for CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently compile in physmap (or new, platform-style, users of physmap) don't get burned. This works pretty well -- the new physmap driver is a drop-in replacement for the old one, and works on said ixp23xx board without any code changes needed. (This should hold as long as users don't touch 'physmap_map' directly.) Once all physmap users have been converted to instantiate their own platform devices, the compat code can go. (Or we decide that we can change all the in-tree users at the same time, and never merge the compat code.)

* ts72xx NAND driverLennert Buytenhek2006-04-30

* mtd: improve parameter parsing for block2mtdJoern Engel2006-04-19
| | | | | | | | | | | | | | | | | | | | Expand the parameter parsing for block2mtd. It now accepts: Ki, Mi, Gi - the official prefixes for binary multiples, see http://physics.nist.gov/cuu/Units/binary.html, ki - mistake on my side and analog to "k" for decimal multiples, KiB, MiB, GiB - for people that prefer to add a "B" for byte, kiB - combination of the above. There were complaints about not accepting "k" for 1024. This has long been common practice, but is known to lead to confusion. Hence the new SI units and hence block2mtd only accepts units that cannot be confused with decimal units. Diverging from common practice doesn't always please people, even if the change is for the better.

* [PATCH] Remove blkmtdJoern Engel2006-04-11
| | | | | | | | | | | | | | | | | | | | | Remove the blkmtd driver. - An alternative exists (block2mtd) that hasn't had bug report for > 1 year. - Most embedded people tend to use ancient kernels with custom patches from mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts them too much. - It's in the way of klibc. The problems caused by pulling blkmtd support are fairly low, while the problems caused by delaying klibc can be fairly substantial. At best, this would be a severe burden on hpa's time.
