Unfortunately not all issues are resolved. To work around an issue with the pl330 dma engine I respun the patch for limiting transfer size in m25p80 driver. As the flash does not contain any sane filesystem and is only likely to be accessed with mtd_debug or similar tool the limit of the dma engine is easily reached. Filesystems using shorter data transfers are less likely to be affected. Thanks Michal Michal Suchanek (11): ARM: dt: Add SPI CS on Samsung Snow board. mtd: spi-nor: Add GD25LQ32C 1.8V SPI NOR flash ID mtd: add debug prints to mtdpart partition parser. mtd: ofpart: do not fail probe when no partitions exist mtd: mtdpart: Do not fail mtd probe when parsing partitions fails. mtd: spi-nor: rework spi nor read and write. mtd: spi-nor: rework write loop MTD: m25p80: Add option to limit SPI transfer size. dma: pl330: fix wording in mcbufsz message spi: add more debug prints in s3c64xx dt: Exynos: add Snow SPI NOR node. .../devicetree/bindings/mtd/jedec,spi-nor.txt | 6 ++ arch/arm/boot/dts/exynos5250-snow.dts | 15 +++- drivers/dma/pl330.c | 4 +- drivers/mtd/devices/m25p80.c | 57 +++++++++++---- drivers/mtd/mtdpart.c | 9 ++- drivers/mtd/ofpart.c | 4 +- drivers/mtd/spi-nor/fsl-quadspi.c | 29 ++++---- drivers/mtd/spi-nor/spi-nor.c | 80 ++++++++++++---------- drivers/spi/spi-s3c64xx.c | 30 ++++++++ include/linux/mtd/spi-nor.h | 8 +-- 10 files changed, 166 insertions(+), 76 deletions(-) -- 2.1.4
