ARM: kirkwood: Basic support for DNS-320 and DNS-325
Add support for the DNS-320 and DNS-325. Describe as much as currently possible in the devicetree files, create a board-dnskw.c for everything else. Changes since last submission (V3) [Addressing comments by]:- * One MACH_DLINK_KIRKWOOD_DT for all dtb files [Grant Likely, Jason Cooper] * Drop brain-dead select "select CONFIG_MTD_OF_PARTS" [Grant Likely] * Don't add NAND support then throw it away immediately after [Grant Likely] * Describe purpose of MPP 41, 42 & 49 Changes since last submission (V2):- * Use IEEE-compliant "okay", rather than "ok" [Scott Wood] Signed-off-by: Jamie Lentin <jm@lentin.co.uk> Signed-off-by: Jason Cooper <jason@lakedaemon.net>hifive-unleashed-5.1
