From: Alessandro Zini <alessandro.zini at siemens.com>

This patch series introduces support for Cypress/Infineon cy15b102q, a 2Mbit
serial SPI F-RAM device.

As the JEDEC-assigned manufacturer ID places the Cypress (Ramtron)
identifier in bank 7, this series also introduces a mechanism to handle eventual
continuation codes (0x7f) that may be prefixed to the actual ID.

Alessandro Zini (3):
  mtd: spi-nor: handle JEDEC manufacturer bank
  mtd: spi-nor: convert existing devices to use mfr_bank
  mtd: spi-nor: add support for Cypress cy15b102q
