Reduce devm_ioremap size to (4 * AHB_BUFER_SIZE) rather than mapping complete QSPI-Memmory as driver is now independent of flash size. Flash of any size can be accessed. Issue was reported on platform where devm_ioremap failure is observed with size > 256M. Error log on LS1021ATWR : fsl-quadspi 1550000.spi: ioremap failed for resource [mem 0x40000000-0x7fffffff] fsl-quadspi 1550000.spi: Freescale QuadSPI probe failed fsl-quadspi: probe of 1550000.spi failed with error -12 This change was also suggested previously: https://patchwork.kernel.org/patch/10508753/#22166385 Suggested-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Kuldeep Singh <kuldeep.singh@nxp.com> Signed-off-by: Ashish Kumar <Ashish.kumar@nxp.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Frieder Schrempf <frieder.schrempf@kontron.de> Link: https://lore.kernel.org/r/1587037399-18672-1-git-send-email-Ashish.Kumar@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
