* mtd: orion_nand: Fix build failure caused by typoPeter Huewe2010-02-101-1/+1
| | | | | | | | | | | | | | | Commit e99030609e27abff7e1a868cb56384c678b09984 ("mtd: orion_nand.c: add error handling and use resource_size()") introduced a build error -- it assigns something to a undeclared variable 'err', whereas the rest of the code uses 'ret' for this task. This patch fixes this typo and thus removes the build failure.

| | | | | | | | | | | | | | | | crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if panic_on_oops is set, so the kernel log buffer is not stored for this case. This patch adds a KMSG_DUMP_KEXEC dump type which gets called when crash_kexec() is invoked. To avoid getting double dumps, the old KMSG_DUMP_PANIC is moved below crash_kexec(). The mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the same way as a panic.

They honored the fact that the bad block marker on 8bit flashes is on byte 5 while on 16bit flashes it is on byte 11. In the Kernel driver this was copied wrong and we ended up with two identical descriptions. Change it so that we have only one description which leaves byte 5 and byte 11 unspecified so that it won't be used by others. Also, rename the descriptions to nand_hw_eccoob_smallpage and nand_hw_eccoob_largepage so that it can't be confused with Nand chip bus widths (what actually happened in this driver) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | mtd: mtdoops: refactor as a kmsg_dumperSimon Kagstrom2009-11-301-133/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last messages which happens before a crash might contain interesting information about the crash. This patch reworks mtdoops using the kmsg_dumper support instead of a console, which simplifies the code and also includes the messages before the oops started. On oops callbacks, the MTD device write is scheduled in a work queue (to be able to use the regular mtd->write call), while panics call mtd->panic_write directly. Thus, if panic_on_oops is set, the oops will be written out during the panic. A parameter to specify which mtd device to use (number or name), as well as a flag, writable at runtime, to toggle wheter to dump oopses or only panics (since oopses can often be handled by regular syslog). The patch was massaged and amended by Artem.
