Subject: [PATCH 4/5] arm: Add support for the Broadcom Northstar SoCs

The original Northstar is an ARM SoC series that comprise
|
||
|
|
BCM4709x and BCM5301x and uses a dual-core Cortex A9, the
|
||
|
|
global timer and a few other things.
|
||
|
|
|
||
|
|
This series should not be confused with North Star Plus
|
||
|
|
(NSP) which is partly supported by U-Boot already.
|
||
|
|
|
||
|
|
The SoC is well supported by the Linux kernel and OpenWrt
|
||
|
|
as it is used in many routers.
|
||
|
|
|
||
|
|
Since we currently don't need any chip-specific quirks
|
||
|
|
and can get the system up from just the device tree, a
|
||
|
|
mach-* directory doesn't even need to be added, just
|
||
|
|
some small Kconfig fragments.
