Pull MTD updates from Brian Norris: "NAND: Quoting Boris: 'This pull request contains only one notable change: - Addition of the MTK NAND controller driver And a bunch of specific NAND driver improvements/fixes. Here are the changes that are worth mentioning: - A few fixes/improvements for the xway NAND controller driver - A few fixes for the sunxi NAND controller driver - Support for DMA in the sunxi NAND driver - Support for the sunxi NAND controller IP embedded in A23/A33 SoCs - Addition for bitflips detection in erased pages to the brcmnand driver - Support for new brcmnand IPs - Update of the OMAP-GPMC binding to support DMA channel description' In addition, some small fixes around error handling, etc., as well as one long-standing corner case issue (2.6.20, I think?) with writing 1 byte less than a page. NOR: - rework some error handling on reads and writes, so we can better handle (for instance) SPI controllers which have limitations on their maximum transfer size - add new Cadence Quad SPI flash controller driver - add new Atmel QSPI flash controller driver - add new Hisilicon SPI flash controller driver - support a few new flash, and update supported features on others - fix the logic used for detecting a fully-unlocked flash And other miscellaneous small fixes" * tag 'for-linus-20160801' of git://git.infradead.org/linux-mtd: (60 commits) mtd: spi-nor: don't build Cadence QuadSPI on non-ARM mtd: mtk-nor: remove duplicated include from mtk-quadspi.c mtd: nand: fix bug writing 1 byte less than page size mtd: update description of MTD_BCM47XXSFLASH symbol mtd: spi-nor: Add driver for Cadence Quad SPI Flash Controller mtd: spi-nor: Bindings for Cadence Quad SPI Flash Controller driver mtd: nand: brcmnand: Change BUG_ON in brcmnand_send_cmd mtd: pmcmsp-flash: Allocating too much in init_msp_flash() mtd: maps: sa1100-flash: potential NULL dereference mtd: atmel-quadspi: add driver for Atmel QSPI controller mtd: nand: omap2: fix return value check in omap_nand_probe() Documentation: atmel-quadspi: add binding file for Atmel QSPI driver mtd: spi-nor: add hisilicon spi-nor flash controller driver mtd: spi-nor: support dual, quad, and WP for Gigadevice mtd: spi-nor: Added support for n25q00a. memory: Update dependency of IFC for Layerscape mtd: nand: jz4780: Update MODULE_AUTHOR email address mtd: nand: sunxi: prevent a small memory leak mtd: nand: sunxi: add reset line support mtd: nand: sunxi: update DT bindings ...

mtd: add arch dependency for MTD_BCM47XXSFLASH symbol

2016-07-19T18:16:49+00:00

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).

For years now we support writing to BCMA SoC serial flash, so don't describe this driver as providing read-only support anymore. Signed-off-by: Rafał Miłecki Signed-off-by: Brian Norris

mtd: st_spi_fsm: only build for ARM

2014-04-17T04:59:29+00:00

COMPILE_TEST allows us to build this driver on other arch'es. But not all arch'es have the right I/O accessors -- particularly, x86 is missing readsl() and writesl(). So just restrict this driver to ARCH_STI. It's still buildable for a multiplatform ARM kernel, so it can get decent compile coverage. Signed-off-by: Brian Norris Acked-by: Lee Jones

mtd: st_spi_fsm: fixup Kconfig dependency

2014-04-14T18:23:01+00:00

I hear that this driver should depend on ARCH_STI, and that "SH" is not actually a real symbol. At the same time, let's allow compile-testing on other ARCH'es. Signed-off-by: Brian Norris Acked-by: Lee Jones Reviewed-by: Marek Vasut

mtd: m25p80: use the SPI nor framework

2014-04-14T18:22:58+00:00

Use the new SPI nor framework, and rewrite the m25p80: (0) remove all the NOR comands. (1) change the m25p->command to an array. (2) implement the necessary hooks, such as m25p80_read/m25p80_write. Tested with the m25p32. Signed-off-by: Huang Shijie Acked-by: Marek Vasut [Brian: rebased] Signed-off-by: Brian Norris
