   9 The original Northstar is an ARM SoC series that comprise
  10 BCM4709x and BCM5301x and uses a dual-core Cortex A9, the
  11 global timer and a few other things.
  12
  13 This series should not be confused with North Star Plus
  14 (NSP) which is partly supported by U-Boot already.
  15
  16 The SoC is well supported by the Linux kernel and OpenWrt
  17 as it is used in many routers.
  18
  19 Since we currently don't need any chip-specific quirks
  20 and can get the system up from just the device tree, a
  21 mach-* directory doesn't even need to be added, just
  22 some small Kconfig fragments.
