2017-02-10mtd: spi-nor: add dt support for Everspin MRAMsUwe Kleine-König1-1/+5
The MR25 family doesn't support JEDEC, so they need explicit mentioning in the list of supported spi IDs. This makes it possible to add these using for example: compatible = "everspin,mr25h40"; There was already an entry for mr25h256. Move that one out of the "keep for compatibility" section and put in a new group for Everspin MRAMs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com>
2017-02-10mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address op codesCyrille Pitchen2-21/+14
This patch renames the SPINOR_OP_* macros of the 4-byte address instruction set so the new names all share a common pattern: the 4-byte address name is built from the 3-byte address name appending the "_4B" suffix. The patch also introduces new op codes to support other SPI protocols such as SPI 1-4-4 and SPI 1-2-2. This is a transitional patch and will help a later patch of spi-nor.c to automate the translation from the 3-byte address op codes into their 4-byte address version.

2017-02-08mtd: bcm47xxsflash: support reading flash out of mapping windowRafał Miłecki2-3/+24
For reading flash content we use MMIO but it's possible to read only first 16 MiB this way. It's simply an arch design/limitation. To support flash sizes bigger than 16 MiB implement indirect access using ChipCommon registers. This has been tested using MX25L25635F.

BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and uses this old ChipCommon-based flash access. Early tests resulted in flash corruptions that were tracked down to using cached MMIO for flash read access. Switch to ioremap_nocache conditionally to support BCM53573 and don't break performance on old MIPS devices.

2016-07-19mtd: add arch dependency for MTD_BCM47XXSFLASH symbolRafał Miłecki1-1/+1
We dropped strict MIPS dependency for bcm47xxsflash driver in: commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of KSEG0ADDR()") but using ioremap_cache still limits building it to few selected architectures only. A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support on non-MIPS SoCs") automatically dropped MIPS dependency for MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris. The bcma change is alright as it doesn't break building bcma code in any way. MTD_BCM47XXSFLASH on the other hand should be limited to archs which need it and can build it (by providing ioremap_cache).

2016-04-26mtd: pmc551: add __init attributeJulia Lawall1-1/+1
Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 00000000000000c6 l F .text.unlikely 000000000000091c fixup_pmc551 And after the change it is as follows: 0000000000000000 l F .init.text 0000000000000917 fixup_pmc551 Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.

2016-04-04mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macrosKirill A. Shutemov1-3/+3
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm. Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable. Let's stop pretending that pages in page cache are special. They are not. The changes are pretty straight-forward: - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN}; - page_cache_get() -> get_page(); - page_cache_release() -> put_page(); This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually. The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later. There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch. virtual patch @@ expression E; @@ - E << (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ expression E; @@ - E >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ @@ - PAGE_CACHE_SHIFT + PAGE_SHIFT @@ @@ - PAGE_CACHE_SIZE + PAGE_SIZE @@ @@ - PAGE_CACHE_MASK + PAGE_MASK @@ expression E; @@ - PAGE_CACHE_ALIGN(E) + PAGE_ALIGN(E) @@ expression E; @@ - page_cache_get(E) + get_page(E) @@ expression E; @@ - page_cache_release(E) + put_page(E) Signed-off-by: Kirill A.

2016-04-04mtd: bcm47xxsflash: use ioremap_cache() instead of KSEG0ADDR()Brian Norris2-6/+26
Using KSEG0ADDR makes code highly MIPS dependent and not portable. Thanks to the fix a68f376 ("MIPS: io.h: Define `ioremap_cache'") we can use ioremap_cache which is generic and supported on MIPS as well now. KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache we use MIPS's __ioremap (and then remap_area_pages). This results in different address (e.g. 0xc0080000) but it still should be cached as expected and it was successfully tested with BCM47186B0. Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a struct resource for access window, but we wren't using it. Use it now and drop duplicated info.

2015-11-19mtd: m25p80: fix module autoloading for "jedec, spi-nor" and "spi-nor"Brian Norris1-1/+10
Commit 43163022927b ("mtd: m25p80: allow arbitrary OF matching for "jedec,spi-nor"") moved the "jedec,spi-nor" handling from the spi_device_id table to the of_match_table, to better handle matching complex device tree compatible strings. With that patch, device tree support works as expected when m25p80.c is built into the kernel. However, that commit ignored the fact that: (1) (non-DT) platform devices might want to use the "spi-nor" string for matching with this driver, rather than picking an arbitrary one like "m25p80" (2) the core SPI uevent/modalias code doesn't yet support kernel module autoloading via of_match_table strings; so for DT-based devices, it will only report (part of) the first compatible string used Problem (1) has been reported previously, and I forgot to patch it up afterward. Problem (2) was noticed recently here: http://lists.infradead.org/pipermail/linux-mtd/2015-October/062369.html https://lkml.org/lkml/2015/11/12/574 Specifically, this patch fixes m25p80.ko module autoloading for cases like this: flash@xxx { compatible = "jedec,spi-nor"; ... }; because modalias of "spi:spi-nor" (the only module loading info provided by the SPI core for this device) will now be listed as an alias in m25p80.ko. Notably, it does *not* help cases like this: flash@xxx { compatible = "vendor,shiny-new-device", "jedec,spi-nor"; ... }; unless we also list "shiny-new-device" in m25p_ids[].
