2018-11-07spi: Add QuadSPI driver for Atmel SAMA5D2Piotr Bugalski
Kernel contains QSPI driver strongly tied to MTD and nor-flash memory. New spi-mem interface allows usage also other memory types, especially much larger NAND with SPI interface. This driver works as SPI controller and is not related to MTD, however can work with NAND-flash or other peripherals using spi-mem interface.

Looks like this driver was initially added to support the NOR on the DA830-EVM (Davinci) board, but the board file update was never merged. Keeping unused drivers just adds to the maintenance burden, so let's remove it if nobody uses it.

2018-11-05mtd: maps: Merge gpio-addr-flash.c into physmap-core.cBoris Brezillon
Controlling some MSB address lines using GPIOs is just a small deviation from the generic physmap logic, and merging those two drivers allows us to share most of the probe logic, which is a good thing. Also, the gpio-addr-flash driver is unused since the removal of the blackfin arch in v4.17, so we can safely remove the old driver without risking breaking existing boards.

2018-11-05mtd: docg3: don't set conflicting BCH_CONST_PARAMS optionArnd Bergmann
I noticed during the creation of another bugfix that the BCH_CONST_PARAMS option that is set by DOCG3 breaks setting variable parameters for any other users of the BCH library code. The only other user we have today is the MTD_NAND software BCH implementation (most flash controllers use hardware BCH these days and are not affected). I considered removing BCH_CONST_PARAMS entirely because of the inherent conflict, but according to the description in lib/bch.c there is a significant performance benefit in keeping it. To avoid the immediate problem of the conflict between MTD_NAND_BCH and DOCG3, this only sets the constant parameters if MTD_NAND_BCH is disabled, which should fix the problem for all cases that are affected. This should also work for all stable kernels. Note that there is only one machine that actually seems to use the DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have the driver disabled, but it almost certainly shows up if we wanted to test random kernels on machines that use software BCH in MTD.

Core changes: * Support non-uniform erase size * Support controllers with limited TX fifo size Driver changes: * m25p80: Re-issue a WREN command after each write access * cadence: Pass a proper dir value to dma_[un]map_single() * fsl-qspi: Check fsl_qspi_get_seqid() return val make sure 4B addressing opcodes are properly handled * intel-spi: Add a new PCI entry for Ice Lake
2018-10-16mtd_blkdevs: convert to blk-mqJens Axboe
Straight forward conversion, using an internal list to enable the driver to pull requests at will. Dynamically allocate the tag set to avoid having to pull in the block headers for blktrans.h, since various mtd drivers use block conflicting names for defines and functions.

2018-10-12mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MBLiu Xiang
If the size of spi-nor flash is larger than 16MB, the read_opcode is set to SPINOR_OP_READ_1_1_4_4B, and fsl_qspi_get_seqid() will return -EINVAL when cmd is SPINOR_OP_READ_1_1_4_4B. This can cause read operation fail.

2018-10-08mtd: spi-nor: fsl-quadspi: Don't let -EINVAL on the busAhmad Fatoum
fsl_qspi_get_seqid() may return -EINVAL, but fsl_qspi_init_ahb_read() doesn't check for error codes with the result that -EINVAL could find itself signalled over the bus. In conjunction with the LS1046A SoC's A-009283 errata ("Illegal accesses to SPI flash memory can result in a system hang") this illegal access to SPI flash memory results in a system hang if userspace attempts reading later on. Avoid this by always checking fsl_qspi_get_seqid()'s return value and bail out otherwise.

2018-10-08mtd: devices: m25p80: Make sure WRITE_EN is issued before each writeYogesh Gaur
Some SPI controllers can't write nor->page_size bytes in a single step because their TX FIFO is too small, but when that happens we should make sure a WRITE_EN command before each write access and READ_SR command after each write access is issued. The core is already taking care of that, so all we have to do here is return the actual number of bytes that were written during the spi_mem_exec_op() operation.
