From ed21cfe207276e2d2883173399dd0380db372e18 Mon Sep 17 00:00:00 2001 From: Ganesan Ramalingam <ganesanr@broadcom.com> Date: Wed, 31 Oct 2012 12:01:42 +0000 Subject: MIPS: Netlogic: Support for XLR/XLS Fast Message Network On XLR/XLS, the cpu cores communicate with fast on-chip devices (e.g. network accelerator, security engine etc.) using the Fast Messaging Network(FMN). The FMN queues and credits needs to be configured and intialized before it can be used. The co-processor 2 on XLR/XLS CPU cores has registers for FMN access, and the XLR/XLS has custom instructions for sending and loading messages. The FMN can deliver also per-cpu interrupts when messages are available at the CPU. This patch adds FMN initialization, adds interrupt setup and handling, and also provides support for sending and receiving FMN messages.
