- Subject: [PATCH 4/5] arm: Add support for the Broadcom Northstar SoCs
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- 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.
