From 0d0632f523fa040b307688ae421a1debf79af2d7 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 15 May 2013 15:37:01 +0200 Subject: arm: kirkwood: convert db-88f6281/db-88f6282 to the Device Tree This commit converts the Marvell DB-88F6281/DB-88F6282 board to the Device Tree. In fact, the code was supporting two different boards: one with the 6281 SoC variant, and one with the 6282 SoC variant. The difference between the two being that the 6281 has one PCIe interface, and the 6282 has two PCIe interfaces. In order to handle that with the Device Tree, we create a 'kirkwood-db.dtsi' file that contains the definitions common to both boards, and 'kirkwood-db-88f6281.dts' and 'kirkwood-db-88f6282.dts' for the definitions specific to each board. This is similar to what is done for the QNAP TS219 Kirkwood platform. We have kept one single Kconfig option, just like it was before.
