* [MTD] chips cfi_cmdset_0002: Prevent timeout raceKonstantin Baidarov2005-11-07
| | | | | | | | | | | | | | | | | | We've noticed that sometimes "MTD do_write_buffer(): software timeout" message was printed out when writing to a Fujitsu NOR flash. It turned out that this was because of a race in the timeout handling do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and sometimes if the timer interrupt handling takes more than one or even two jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just after chip_ready() call, the driver bails out from a ready polling loop despite the chip has actually become ready while all those interrupts were handled. To deal with this issue, extra check for chip ready is neccessary on timeout expiration (and the checks should better be reordered). As do_write_oneword() uses the same approach, it needs to also be changed.

* [MTD] maps/plat-ram: Avoid gcc 4.0 warningThomas Gleixner2005-11-06
| | | | | | | | | The assignement of a "const char *" to a "char *" variable is emitting a warning with gcc 4.0. We cannot change mtd->name to "const char *" as we have dynamic assignements of the name. So casting is the correct solution here Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [MTD] NAND: nand_write_ecc memory and OOB corruptionTodd Poynor2005-11-06
| | | | | | | | | | Nathan Roberts noticed the nand_write_ecc index into oobbuf goes out of bounds when crossing an erase block boundary, causing incorrect OOB data to be written and corrupting memory.

* [JFFS2] Add erase block summary support (mount time improvement)Ferenc Havasi2005-11-06
| | | | | | | | | | | | | | | | | | The goal of summary is to speed up the mount time. Erase block summary (EBS) stores summary information at the end of every (closed) erase block. It is no longer necessary to scan all nodes separetly (and read all pages of them) just read this "small" summary, where every information is stored which is needed at mount time. This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During the mount process if there is no summary info the orignal scan process will be executed. EBS works with NAND and NOR flashes, too. There is a user space tool called sumtool to generate this summary information for a JFFS2 image.
