Subject: [dts] [PATCH 4/6] nics: add support for Boulder Rapid
Date: Wed,  3 Feb 2016 14:50:15 +0800	[thread overview]
Message-ID: <1454482217-25147-5-git-send-email-yong.liu@intel.com> (raw)
In-Reply-To: <1454482217-25147-1-git-send-email-yong.liu@intel.com>

Boulder Rapid just like RedRockCanyou, it also has two PEPs and EPLs.
The major difference is that RedRockCanyou has Rangely control plan
process. But Boulder Rapid do not have.
Another difference is that Special for pci address, Boulder Rapid port0 will
be assigned higher pci address.
