Sebastian Huber c93f0f01e5 arm: Fix PMSA regions for contiguous sections
Sections with identical attributes may be contiguous with a respective
begin and end address which is not on a minimum region boundary.  The
begin address is aligned down to the region base address.  The end
address is aligned up to the region end address.  Account for this in
the check for contiguous sections.

Update #4202.

Real-Time Executive for Multiprocessing Systems (RTEMS)
-------------------------------------------------------

RTEMS, Real-Time Executive for Multiprocessor Systems, is a real-time executive
(kernel) which provides a high performance environment for embedded
applications with the following features:

 - standards based user interfaces
 - multitasking capabilities
 - homogeneous and heterogeneous multiprocessor systems
 - event-driven, priority-based, preemptive scheduling
 - optional rate monotonic scheduling
 - intertask communication and synchronization
 - priority inheritance
 - responsive interrupt management
 - dynamic memory allocation
 - high level of user configurability
 - open source with a friendly user license
