It use blockpage instead of a pair (block, page). It can also cover a small chunk access. 0x00, 0x20, 0x40 and so on. And in JFFS2 behavior, sometimes it reads two pages alternatively. e.g., It first reads A page, B page and A page. So we check another bufferram to find requested page.

When write-verify is enabled (CONFIG_MTD_ONENAND_VERIFY_WRITE), the data written is read back and compared. The comparison was being made between dataRAM buffers, but this does not verify that the data made it to the dataRAM correctly in the first place. This patch amends write-verify to compare back to the original buffer. It also now verifies sub-page writes.

inlined below is the patch that adds physmap driver for of_device. It's an MTD part of the two-part support for flash/ROM devices based on Open Firmware descriptions. The arch part (currently only PowerPC which is no surprise) was introduced to powerpc folks earlier and recently the older version of the powerpc part has been included into the powerpc.git tree (see http://www.kernel.org/git/?p=linux/kernel/git/paulus/powerpc.git;a=commitdiff;h=28f9ec349ae47c91768b7bc5607db4442c818e11). drivers/mtd/maps/Kconfig | 9 + drivers/mtd/maps/Makefile | 1 drivers/mtd/maps/physmap_of.c | 255 ++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 265 insertions(+) Signed-off-by: NVitaly Wool <vwool@ru.mvista.com> Signed-off-by: NSergey Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: NDavid Woodhouse <dwmw2@infradead.org>

RedBoot supports storing the FIS directory and the RedBoot configuration area in the same block of flash memory. This is not the most common RedBoot configuration, but it is used on commercially available boards supported by the kernel. A recent patch to mtd/redboot.c (http://lkml.org/lkml/2006/3/20/410) which corrected the skipping of deleted table entries has exposed the latent problem of the kernel redboot parser running off the end of the FIS directory and interpreting the RedBoot configuration information as table entries. This patch terminates the table parsing when the first truly empty entry is found (table entry deletion only clears the first byte of the name, so two cleared bytes in a row indicates the end of the table), thereby supporting the combined redboot FIS directory and RedBoot configuration information flash layout scenario.
