Subject: [PATCH 0/2] Support parameter page and Redesign Micron SPI NAND

Parameter page is supported by some of the manufacturers and instead of
maintaining spinand_info structure for each flash it is better to use
the parameter page to get the flash info. As I have seen the different
datasheets, command required to access parameter page is same across the
manufacturers.

Micron SPI NAND flashes support parameter page, instead of adding 8
devices I thought it is better to re-design the code using parameter
page.

Shivamurthy Shastri (2):
  mtd: spinand: Add function to read parameter page
  mtd: spinand: micron: Support for all Micron SPI NAND flashes
