-Subject: [PATCH] mtd: parsers: add TP-Link SafeLoader partitions table parser
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This parser deals with most TP-Link home routers. It reads info about
-partitions and registers them in the MTD subsystem.
-
-Example from TP-Link Archer C5 V2:
-
-spi-nor spi0.0: s25fl128s1 (16384 Kbytes)
-15 tplink-safeloader partitions found on MTD device spi0.0
-Creating 15 MTD partitions on "spi0.0":
-0x000000000000-0x000000040000 : "fs-uboot"
-0x000000040000-0x000000440000 : "os-image"
-0x000000440000-0x000000e40000 : "rootfs"
