2017-02-10mtd: spi-nor: improve macronix_quad_enable()Cyrille Pitchen
The patch checks whether the Quad Enable bit is already set in the Status Register. If so, the function exits immediately with a successful return code.

2017-02-10mtd: spi-nor: Add support for S3AN spi-nor devicesRicardo Ribalda
Xilinx Spartan-3AN FPGAs contain an In-System Flash where they keep their configuration data and (optionally) some user data. The protocol of this flash follows most of the spi-nor standard. With the following differences: - Page size might not be a power of two. - The address calculation (default addressing mode). - The spi nor commands used. Protocol is described on Xilinx User Guide UG333 Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Cc: Boris Brezillon <boris.brezillon@free-electrons.com> Cc: Brian Norris <computersforpeace@gmail.com> Cc: Marek Vasut <marek.vasut@gmail.com> Reviewed-by: Marek Vasut <marek.vasut@gmail.com> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com>

This change simplifies main parsing loop logic a bit. In future it may be useful for moving TRX support to separated module / parser (if we implement support for them at some point). Finally parsing TRX at the end puts us in a better position as we have better flash layout knowledge. It may be useful e.g. if it appears there is more than 1 TRX partition.

2017-02-08mtd: physmap_of: add a hook for Gemini flash probingLinus Walleij
In order to support device tree probing of Gemini NOR flash chips, a certain register in the syscon needs to be poked to enable parallel flash mode. Such things used to happen in "necessarily different" board file code, and this indeed was also done for the Gemini, so the MTD driver could treat it as any memory-mapped NOR flash, but this is not the way in the future: board files need to go, and hardware concerns distributed down to the applicable drivers. This adds a hook in the same way that the Versatile did: if the Kconfig symbol is not selected the net total of supporting Gemini should be zero bytes of added code. To live up to this promise, also the return value error print from the Versatile extra probe call get to be removed in this patch, all printing need to happen in the add-ons.

Instead of keeping two levels of indirection for requests types, fold it all into the operations.

2016-12-01mtd: Allocate bdi objects dynamicallySteve Longerbeam
The MTD backing dev info objects mtd_bdi was statically allocated. So when MTD is built as a loadable module, this object fall in the vmalloc address space. The problem with that, is that the BDI APIs use wake_up_bit(), which calls virt_to_page() to retrieve the memory zone of the page containing the wait_queue to wake up, and virt_to_page() is not valid for vmalloc or highmem addresses. Fix this by allocating the BDI objects dynamically with kmalloc. The objects now fall in the logical address space so that BDI APIs will work in all cases (mtd builtin or module).
