Subject: [PATCH] mtd: parsers: add TP-Link SafeLoader partitions table parser

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"

|
