From 1ae842de1dd8051cbb65b396b6f029d07f992641 Mon Sep 17 00:00:00 2001 From: Alexandre Bounine Date: Tue, 2 Aug 2016 14:06:57 -0700 Subject: rapidio: modify for rev.3 specification changes Implement changes made in RapidIO specification rev.3 to LP-Serial Physical Layer register definitions: - use per-port register offset calculations based on LP-Serial Extended Features Block (EFB) Register Map type (I or II) with different per-port offset step (0x20 vs 0x40 respectfully). - remove deprecated Parallel Physical layer definitions and related code.
