These SoCs are network packet processors (switch chips) with integrated ARMv7 cores. They share a great deal of commonality with the Armada-XP CPUs. Signed-off-by: Chris Packham <judge.packham@gmail.com> --- There are actually a number of IDs for these chips, probably a dozen in total. I haven't enumerated them all in this patch, the 98DX4251, 98DX3336 and 98DX3236 are the base versions in their respective ranges. These 3 IDs also happen to suit my immediate need but I can add the additional ones in an follow up patch or a re-roll of this one. arch/arm/mach-mvebu/cpu.c | 14 ++++++++++++++ arch/arm/mach-mvebu/include/mach/cpu.h | 1 + arch/arm/mach-mvebu/include/mach/soc.h | 3 +++ 3 files changed, 18 insertions(+)
