Currently fdt_check_header() performs only some rudimentary checks, which is not really what the name suggests. This strengthens fdt_check_header() to check as much about the blob as is possible from the header alone: as well as checking the magic number and version, it checks that the total size is sane, and that all the sub-blocks within the blob lie within the total size. * This broadens the meaning of FDT_ERR_TRUNCATED to cover all sorts of improperly terminated blocks as well as just a structure block without FDT_END. * This makes fdt_check_header() only succeed on "complete" blobs, not in-progress sequential write blobs. The only reason this didn't fail before was that this function used to be called by many RO functions which are supposed to also work on incomplete SW blobs.

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
