Sebastian Huber 62598e8db1 bsps/mips: Build the libdl tests of three BSPs
The hurricane, rbtx4925 and rbtx4938 BSPs excluded dl01 to dl13.  The
exclusion dates from 2015 and answers a link failure of dl01.  The
build of that era passed the compiler flags to rtems-syms as a string
and let the tool call the compiler.  The string lost -EL, so the tool
built a big endian object for a little endian target and the link
rejected it.

The waf build runs rtems-syms with -S, which writes a C source file,
and compiles that file itself with the flags of the BSP.  The flag
cannot get lost.

Drop the exclusion of the three BSPs.  Twelve tests return, because
dl13 belongs to arm.  The other users of the item keep it.

No simulator runs these three BSPs, so the link is the only evidence
available.  The link is what the report named.

Update #2279.

Real-Time Executive for Multiprocessing Systems

RTEMS 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.
  • Symmetric Multiprocessing (SMP):
    • Cluster scheduling: Job-level fixed prority scheduler (EDF) with support for one-to-one and one-to-all thread to processor affinities.
    • Locking protocols with transitive priority inheritance, priority ceiling, MRsP and OMIP.
  • Event-driven, priority-based, preemptive scheduling.
  • Scalable timer and timeout support.
  • Optional rate monotonic scheduling.
  • Intertask communication and synchronisation.
  • Priority inheritance.
  • Responsive interrupt management.
  • Dynamic memory allocation.
  • Dynamic code loading using run-time link editing.
  • File systems, IMFS, FAT, RFS, JFFS, NSFv4 (with LibBSD)
  • High level of user configurability.
  • Link-time configurable schedulers.
  • Linker-set based initialization (similar to global C++ constructors).
  • Drivers for I2C, SPI and LibBSD has NIC, USB, SD/MMC and Framebuffer.
  • Open source with a friendly user license.
