2014-03-26MIPS: BCM47XX: Add Belkin F7Dxxxx board detectionCody P Schafer
Add a few Belkin F7Dxxxx entries, with F7D4401 sourced from online documentation and the "F7D7302" being observed. F7D3301, F7D3302, and F7D4302 are reasonable guesses which are unlikely to cause mis-detection.

2014-01-30Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds
Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.
