[PATCH v2 0/8] mtd: spi-nor: spansion: Add support for Infineon S28HS02GT

[Takahiro Kuwano]

Hi,

I tested with the following devices, as this series updates the code used by
other SEMPER flash devices than S28HS02GT.
 - S28HS02GT(Octal, multi-chip)
 - S28HS01GT(Octal, single-chip)
 - S25HS02GT(Quad, multi-chip)
 - S25HS01GT(Quad, single-chip)
 - S25FS256T(Quad, single-chip)

Thanks,
Takahiro
