no-wp:
type: boolean
description:
The status register write disable (SRWD) bit in status register, combined
with the WP# signal, provides hardware data protection for the device. When
the SRWD bit is set to 1, and the WP# signal is either driven LOW or hard
strapped to LOW, the status register nonvolatile bits become read-only and
the WRITE STATUS REGISTER operation will not execute. The only way to exit
this hardware-protected mode is to drive WP# HIGH. If the WP# signal of the
flash device is not connected or is wrongly tied to GND (that includes internal
pull-downs) then status register permanently becomes read-only as the SRWD bit
cannot be reset. This boolean flag can be used on such systems to avoid setting
the SRWD bit while writing the status register. WP# signal hard strapped to GND
can be a valid use case.

title: Seattle Image Partitions
description: The SEAttle iMAge (SEAMA) partition is a type of partition
used for NAND flash devices. This type of flash image is found in some
D-Link routers such as DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L,
DIR890L and DCH-M225, as well as in WD and NEC routers on the ath79
(MIPS), Broadcom BCM53xx, and RAMIPS platforms. This partition type
does not have children defined in the device tree, they need to be
detected by software.
