[PATCH] mtd: spi-nor: micron-st: Add n25q064a WP support

From: Brian Norris
Date: Fri Jul 26 2024 - 14:58:41 EST


These flash chips are used on Google / TP-Link / ASUS OnHub devices, and
OnHub devices are write-protected by default (same as any other
ChromeOS/Chromebook system). I've referred to datasheets, and tested on
OnHub devices.
