[PATCH v3 0/2] mtd: spi-nor: spansion: Add support for Infineon S25FS256T

[tkuw584924 at gmail.com]

From: Takahiro Kuwano <Takahiro.Kuwano at infineon.com>

Infineon S25FS256T is 256Mbit Quad SPI NOR flash. This series updates
RD_ANY_REG_OP macro to support dummy cycles and then adds ID and fixups
for S25FS256T.
