The patch titled
Subject: rapidio: modify for rev.3 specification changes
has been removed from the -mm tree. Its filename was
rapidio-modify-for-rev3-specification-changes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexandre Bounine <alexandre.bounine@xxxxxxx>
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.
