[U-Boot] [PATCH 0/2] Disable hybrid mode for SPANSION S25FS-S family

[Rajat Srivastava]

The S25FS-S family physical sectors may be configured as a hybrid
combination of eight 4-kB parameter sectors at the top or bottom
of the address space with all but one of the remaining sectors
being uniform size. The default status of the flash is the hybrid
architecture.

Since the parameter sectors and the uniform sectors have different
erase commands, it is a problem to implement erase functionality for
hybrid mode in current U-boot code. Also, enabling hybrid mode doesn't
provide any significant benefit.

There is a configuration option to disable the hybrid mode so that all
sectors are of uniform size (256 kbytes). This set of patches disables
the above mentioned hybrid mode in Spansion S25FS-S family of flashes.
