GetMemoryMap(), handling of no-map DT property #55

Closed xypron closed 2 years ago

xypron commented 4 years ago

Closes: #52

The no-map property of the /reserved-memory device tree nodes is used to signal that a memory region shall not be accessed by the operating system, even not via speculative access.

/reserved-memory nodes without the no-map property describe memory that have special usage by the operating system.

This difference has to be reflected in the memory map returned by GetMemoryMap().
