For Micron spi nor device, when erase/program operation fails, especially the failure results from intending to modify protected space, spi-nor upper layers still get the return which shows the operation succeeds. This is because current spi_nor_fsr_ready() only uses FSR bit.7 (flag status register) to check device whether ready. This patch fixes this issue by checking relevant error bits in FSR. The FSR is a powerful tool to investigate the status of device, checking information regarding what the memory is actually doing and detecting possible error conditions.

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.
