-Subject: [PATCH] bus: mvebu-mbus: provide api for obtaining IO and DRAM window
- information
-
-This commit enables finding appropriate mbus window and obtaining its
-target id and attribute for given physical address in two separate
-routines, both for IO and DRAM windows. This functionality
-is needed for Armada XP/38x Network Controller's Buffer Manager and
-PnC configuration.
