S25FS-S family supports SMPT that helps to detect sector layout settings in configuration registers, but some of parameters in the table are wrong or undetermined so the fixups below are required. Read Any Register op is used to read configuration registers that related to sector map. The op requires 8 cycles latency by default. Implement smpt_read_dummy() to set correct dummy cycles. Map ID is structured by combination of CR3NV[3], CR1NV[2], and CR3NV[1]. However, in S25FS512S, CR3NV[1] is RFU and always 0, while map IDs defined in the table assume it is always 1. Implement smpt_map_id() to fix map ID for S25FS512S. Other densities in S25FS-S family (256Mb and 128Mb) don't need this fix as CR3NV[1] in those chips is configurable and map IDs are correctly defined in SMPT.

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 reStructuredText 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.
