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.

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: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

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 <dbrownell@users.sourceforge.net> 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.

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.
