Some of Infineon SPI NOR flash devices support hybrid sector layout that overlays 4KB sectors on a 256KB sector and SPI NOR framework recognizes that by parsing SMPT and construct params->erase_map. The hybrid sector layout is similar to CFI flash devices that have small sectors on top and/or bottom address. In case of CFI flash devices, the erase map information is parsed through CFI table and populated into mtd->eraseregions so that users can create MTD partitions that aligned with small sector boundaries. This patch provides the same capability to SPI NOR flash devices that have non-uniform erase map.

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.
