SPI/MTD: mtd_dataflash oops prevention

2007-01-09T02:23:31+00:00

Return a fault code if the Dataflash driver runs into a "no device present" error when the MISO line has a pulldown (it currently expects a pullup), so that rmmod won't oops. Signed-off-by: David Brownell Signed-off-by: Adrian Bunk

[PATCH] mtd_dataflash, fix block vs page erase

2006-03-14T15:57:17+00:00

Fix a bug in the block-erase optimization for Dataflash; it was using block erase even for smaller segments that need page erase. That wouldn't matter for JFFS2, which never erases less than one block (sometimes several blocks), but for other callers it might.

[PATCH] Unlinline a bunch of other functions

2006-01-15T02:27:06+00:00

Remove the "inline" keyword from a bunch of big functions in the kernel with the goal of shrinking it by 30kb to 40kb Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Acked-by: Jeff Garzik Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] spi: misc fixes

2006-01-14T00:29:56+00:00

This collects some small SPI patches that seem to be missing from the MM tree: - spi_butterfly kbuild hooks got dropped somehow; this restores them - quick fix for a (theoretical?) m25p80_write() oops noted by Andrew - quick fix for a potential config-specific oops for mtd_dataflash() - minor doc tweaks Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman

[PATCH] spi: use linked lists rather than an array

2006-01-14T00:29:56+00:00

This makes the SPI core and its users access transfers in the SPI message structure as linked list not as an array, as discussed on LKML. From: David Brownell Updates including doc, bugfixes to the list code, add spi_message_add_tail(). Plus, initialize things _before_ grabbing the locks in some cases (in case it grows more expensive). This also merges some bitbang updates of mine that didn't yet make it into the mm tree.

[PATCH] spi: M25 series SPI flash

2006-01-14T00:29:55+00:00

This was originally a driver for the ST M25P80 SPI flash. It's been updated slightly to handle other M25P series chips. For many of these chips, the specific type could be probed, but for now this just requires static setup with flash_platform_data that lists the chip type (size, format) and any default partitioning to use.

[PATCH] spi: mtd dataflash driver

2006-01-14T00:29:54+00:00

This is a conversion of the AT91rm9200 DataFlash MTD driver to use the lightweight SPI framework, and no longer be AT91-specific. It compiles down to less than 3KBytes on ARM. The driver allows board-specific init code to provide platform_data with the relevant MTD partitioning information, and hotplugs. This version has been lightly tested. Its parent at91_dataflash driver has been pretty well banged on, although kernel.org JFFS2 dataflash support was acting broken the last time I tried it.

[PATCH] blkmtd: use clear_page_dirty()

2005-12-12T16:57:41+00:00

SetPageDirty() and ClearPageDirty() are low-level thing which filesystems shouldn't be using. They bypass dirty page accounting. Cc: David Woodhouse Acked-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[MTD] Make functions static, include header files with prototypes

2005-11-29T18:54:58+00:00

This patch contains the following possible cleanups: - every file should #include the headers containing the prototypes for it's global functions - make needlessly global functions static Signed-off-by: Adrian Bunk Signed-off-by: Andrew Morton Signed-off-by: Thomas Gleixner
