+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.
