Subject: [PATCH 0/4] enabling Advanced protection and security features

From: Shivamurthy Shastri <sshivamurthy@...ron.com>

Standard protection features in SPI NOR flashes are legacy and offer a
simple way to protect the memory array against accidental or unwanted
modification of its content.

These patches enable the support for advanced sector protection which
protects memory from accidentally corrupting code and data stored, and
it also prevents malicious attacks that could intentionally modify the
code or data stored in the memory.

Micron Flashes offer some of the advanced protection methods using
volatile lock bits, non-volatile lock bits, global freeze bits, and
password.

  mtd: spi-nor: add advanced protection and security features support
  mtd: add advanced protection and security ioctls
  mtd: spi-nor: micron-st: add mt25qu128abb and mt25ql128abb
