Subject: [PATCH 034/203] 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:

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:
