Add MODULE_ALIAS() to the hotpluggable MTD NAND platform drivers, to re-enable auto loading. NOTE: at91_nand for some reason disallows modular builds.

* | [MTD] [NAND] fix possible Ooops in rfc_from4Sebastian Siewior2008-04-221-21/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found this while I was looking how the rs_lib is working. The rs_decoder is initialized _after_ the nand core code read the BBT table and _after_ the partition table has been added. The driver has a private BBT description which is in located in flash data so we Ooops if there is a bit flip _or_ if a bit flips while reading the partition table. This patch moves the initialization of the rs_lib before the first possible access by nand core.

| | * mtd: fix broken state in CFI driver caused by FL_SHUTDOWNAlexey Korolev2008-04-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | THe CFI driver in 2.6.24 kernel is broken. Not so intensive read/write operations cause incomplete writes which lead to kernel panics in JFFS2. We investigated the issue - it is caused by bug in FL_SHUTDOWN parsing code. Sometimes chip returns -EIO as if it is in FL_SHUTDOWN state when it should wait in FL_PONT (error in order of conditions). The following patch fixes the bug in state parsing code of CFI. Also I've added comments to notify developers if they want to add new case in future.

Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MTDs are well suited for logging critical data and the mtdoops driver allows kernel panics/oops to be written to flash in a blackbox flight recorder fashion allowing better debugging and analysis of crashes. Any kernel oops in user context can be easily handled since the kernel continues as normal and any queued mtd writes are scheduled. Any kernel oops in interrupt context results in a panic and the delayed writes will not be scheduled however. The existing mtd->write function cannot be called in interrupt context so these messages can never be written to flash. This patch adds a panic_write function pointer that drivers can optionally implement which can be called in interrupt context. It is only intended to be called when its known the kernel is about to panic and we need to write to succeed. Since the kernel is not going to be running for much longer, this function can break locks and delay to ensure the write succeeds (but not sleep).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the physmap mapping driver to support multiple resources for non-identical NOR chips that will be concatenated together when selected. This is needed for example for Intel 48F4400 512MBit chips, since they consist of 2 single different NOR chips with different geometries. The first (lower) one has botton boot sectors and the 2nd (upper) has top boot sectors. This currently isn't handled correctly by calling the physmap driver once with only one resource covering both chips in one memory region. The same geometrie is used for both chips. With this patch the following resource structure can be used to describe the 48F4400 chip correctly: static struct resource board_nor_resource[] = { [0] = { .start = 0xf8000000, .end = 0xfbffffff, .flags = IORESOURCE_MEM, }, [1] = { .start = 0xfc000000, .end = 0xffffffff, .flags = IORESOURCE_MEM, } }; Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
