According to the datasheet, the HW sequencer has a predefined list of opcodes, with only the erase opcode being programmable in LVSCC and UVSCC registers. If these registers don't contain a valid erase opcode (eg: BIOS does not program it), erase cannot be done using the HW sequencer, even though the erase operation does not report any error, the flash remains not erased. If such register setting is detected, let's fall back to use the SW sequencer to erase instead.

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.
