The MMIO access framework consists of an abstraction for a contiguous MMIO area with a base address set dynamically. Within this class 'Mmio' are declarations for 'Register' and 'Subreg'. These two can be parameterized statically via template parameters to create arbitrary MMIO structures. Whereas 'Register' relies to a POD like subregion of 'Mmio', 'Subreg' relies to a MMIO region within a specific 'Register' and therefore is smaller or equal then the storage type of its superior 'Register'. Furthermore with 'Reg_array' and 'Subreg_array', there exists the possibility to handle arrays of uniform contiguous registers or subregs by index. 'Subreg_array' therefore abstracts from the width boundary of its superior 'Register' and handles a steady distance between its members in addition. Both also check array size limits. Related to issue #69.
This is generic part of the Genode implementation. It consists of two parts: :_Core_: is the ultimate root of the Genode application tree and provides abstractions for the lowest-level hardware resources such as RAM, ROM, CPU, and generic device access. All generic parts of Core can be found here - for system-specific implementations refer to the appropriate 'base-<system>' directory. :_Base libraries and protocols_: that are used by each Genode component to interact with other components. This is the glue that holds everything together.
