If the operating system -+choses to use a different set of mbus windows, it must ensure that any address -+translations performed from downstream devices are adapted accordingly. -+ -+The operating system may insert additional mbus windows that do not conflict -+with the ones listed in the ranges, e.g. for mapping PCIe devices. -+As a special case, the internal register window must be set up by the boot -+loader at the address listed in the ranges property, since access to that region -+is needed to set up the other windows. -+ -+** Example -+ -+See the example below, where a more complete device tree is shown: -+ -+ soc { -+ compatible = "marvell,armadaxp-mbus", "simple-bus"; -+ controller = <&mbusc>; -+ -+ ranges = <MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000 /* internal-regs */ -+ MBUS_ID(0x01, 0x1d) 0 0 0xfff00000 0x100000 -+ MBUS_ID(0x01, 0x2f) 0 0 0xf0000000 0x8000000>; -+ -+ bootrom { -+ compatible = "marvell,bootrom"; -+ reg = <MBUS_ID(0x01, 0x1d) 0 0x100000>; -+ }; -+ -+ devbus-bootcs { -+ status = "okay"; -+ ranges = <0 MBUS_ID(0x01, 0x2f) 0 0x8000000>; -+ -+ /* NOR */ -+ nor { -+ compatible = "cfi-flash"; -+ reg = <0 0x8000000>; -+ bank-width = <2>; -+ }; -+ }; -+ -+ pcie-controller { -+ compatible = "marvell,armada-xp-pcie"; -+ status = "okay"; -+ device_type = "pci"; -+ -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ ranges = -+ <0x82000000 0 0x40000 MBUS_ID(0xf0, 0x01) 0x40000 0 0x00002000 /* Port 0.0 registers */ -+ 0x82000000 0 0x42000 MBUS_ID(0xf0, 0x01) 0x42000 0 0x00002000 /* Port 2.0 registers */ -+ 0x82000000 0 0x44000 MBUS_ID(0xf0, 0x01) 0x44000 0 0x00002000 /* Port 0.1 registers */ -+ 0x82000000 0 0x48000 MBUS_ID(0xf0, 0x01) 0x48000 0 0x00002000 /* Port 0.2 registers */ -+ 0x82000000 0 0x4c000 MBUS_ID(0xf0, 0x01) 0x4c000 0 0x00002000 /* Port 0.3 registers */ -+ 0x82000800 0 0xe0000000 MBUS_ID(0x04, 0xe8) 0xe0000000 0 0x08000000 /* Port 0.0 MEM */ -+ 0x81000800 0 0 MBUS_ID(0x04, 0xe0) 0xe8000000 0 0x00100000 /* Port 0.0 IO */>; -+ -+ -+ pcie@1,0 { -+ /* Port 0, Lane 0 */ -+ status = "okay"; -+ }; -+ }; -+ -+ internal-regs { -+ compatible = "simple-bus"; -+ #address-cells = <1>; -+ #size-cells = <1>; -+ ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>; -+ -+ mbusc: mbus-controller@20000 { -+ reg = <0x20000 0x100>, <0x20180 0x20>; -+ }; -+ -+ interrupt-controller@20000 { -+ reg = <0x20a00 0x2d0>, <0x21070 0x58>; -+ }; -+ }; -+ }; diff --git a/target/linux/mvebu/patches-3.10/0066-PCI-mvebu-Adapt-to-the-new-device-tree-layout.patch b/target/linux/mvebu/patches-3.10/0066-PCI-mvebu-Adapt-to-the-new-device-tree-layout.patch deleted file mode 100644 index c34ecb6..0000000 --- a/target/linux/mvebu/patches-3.10/0066-PCI-mvebu-Adapt-to-the-new-device-tree-layout.patch +++ /dev/null @@ -1,304 +0,0 @@ -From 60538f9841697cd4539d353afd8a7f51cd17e4af Mon Sep 17 00:00:00 2001 -From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> -Date: Fri, 5 Jul 2013 14:54:17 +0200 -Subject: [PATCH 066/203] PCI: mvebu: Adapt to the new device tree layout - -The new device tree layout encodes the window's target ID and attribute -in the PCIe controller node's ranges property.

However, the primary function of -of_irq_parse_raw() is to check for translations due to the presence of -one or more interrupt-map properties. The actual placing of the data -into an of_phandle_args structure is trivial. If it is refactored to -accept an of_phandle_args structure directly, then it becomes possible -to consume of_phandle_args from other sources. This is important for an -upcoming patch that allows a device to be connected to more than one -interrupt parent. It also simplifies the code a bit. - -The biggest complication with this patch is that the old version works -on the interrupt specifiers in __be32 form, but the of_phandle_args -structure is intended to carry it in the cpu-native version. A bit of -churn was required to make this work.
