| | | | | | | | | | | | | | | | | | | | | | | | | | | The read-while-load method of reading from OneNAND needs to allow for the change of bufferRAM address at the boundary between the two chips in a double density (DDP) device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Vitaly Wool <vwool@ru.mvista.com> Signed-off-by: Sergey Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
| * | [MTD] Support combined RedBoot FIS directory and configuration areaRod Whitby2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | [MTD] Use EXPORT_SYMBOL_GPL() for exported symbols.David Woodhouse2006-11-29

The author always intended his code to be released under the GPL, and believes that any new interpretation of 'EXPORT_SYMBOL' as being any different from 'EXPORT_SYMBOL_GPL' is entirely invalid; the GPL requires that _all_ exports have the semantics of the new 'EXPORT_SYMBOL_GPL', which means the extra four characters are entirely redundant. But since those four extra characters trigger the check for illegal modules in a way that just EXPORT_SYMBOL does not, it's useful to change anyway. This action in no way indicates an admission that there is any legal distinction between the two states, and in particular does not indicate that the author believes that non-GPL modules may use symbols exported with EXPORT_SYMBOL alone.
