+* **Added generic EAL API for I/O device memory read/write operations.**
+
+ This API introduces 8-bit, 16-bit, 32bit, 64bit I/O device
+ memory read/write operations along with the relaxed versions.
+
+ The weakly-ordered machine like ARM needs additional I/O barrier for
+ device memory read/write access over PCI bus.
+ By introducing the EAL abstraction for I/O device memory read/write access,
+ The drivers can access I/O device memory in architecture-agnostic manner.
+ The relaxed version does not have additional I/O memory barrier, useful in
+ accessing the device registers of integrated controllers which
+ implicitly strongly ordered with respect to memory access.
