ARM: mvebu: fix length of ethernet registers in mv78260 dtsi The length of the registers area for the Marvell 370/XP Ethernet controller was incorrect in the .dtsi: 0x2500, while it should have been 0x4000. This problem wasn't noticed because there used to be a static mapping for all the MMIO register region set up by ->map_io(). The register length was fixed in all the other device tree files, except from the armada-xp-mv78260.dtsi, in the following commit: commit cf8088c5cac6ce20d914b9131533844b9291a054 Author: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Date: Tue May 21 12:33:27 2013 +0200 arm: mvebu: fix length of Ethernet registers area in .dtsi This commit fixes a kernel panic in mvneta_probe(), when the kernel tries to access the unmapped registers: [ 163.639092] mvneta d0070000.ethernet eth0: mac: 6e:3c:4f:87:17:2e [ 163.646962] mvneta d0074000.ethernet eth1: mac: 6a:04:4e:6f:f5:ef [ 163.654853] mvneta d0030000.ethernet eth2: mac: 2a:99:19:19:fc:4c [ 163.661258] Unable to handle kernel paging request at virtual address f011bcf0 [ 163.668523] pgd = c0004000 [ 163.671237] [f011bcf0] *pgd=2f006811, *pte=00000000, *ppte=00000000 [ 163.677565] Internal error: Oops: 807 [#1] SMP ARM [ 163.682370] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-rc6-01850-gba0682e #11 [ 163.690046] task: ef04c000 ti: ef03e000 task.ti: ef03e000 [ 163.695467] PC is at mvneta_probe+0x34c/0xabc [...] Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
