-Subject: [PATCH 16/29] 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.
