Some manufacturers may use different bit to set QE on different memories. The GD25Q256 from GigaDevice is an example, which uses S6(bit 6 of the Status Register-1) to set QE, which is different with other supported memories from GigaDevice that use S9(bit 1 of the Status Register-2). This makes it is impossible to select the quad enable method by distinguishing the MFR. This patch introduce a quad_enable function which can be set per memory in the flash_info list table.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
