If someone manages to open a file before rtems_libio_post_driver is run,
open() may allocate a file number other than 0 for stdin. This leads to
a silent failure of the logic in rtems_libio_post_driver, and confusing
behavior because your BSP behaves as if it doesn't have a console.
Instead of failing silently, raise an internal error if open() succeeds
but gives us an unexpected file number for stdin.

The block of embedded assembly language which creates a section
to add auto-loading of the Python pretty printing scripts was
getting this warning on all ARM BSPs.
/tmp/ccMGaqij.s: Assembler messages:
/tmp/ccMGaqij.s:19: missing merge / string entity size, 1 assumed
This was because the @ symbol is a comment on ARM. Changing to
a % as suggested on the binutils mailing list resolved the problem.
Define the RTEMS version in the wscript. Optionally use a VERSION file
to change the default values of the wscript. Allow the command line
option --rtems-version to override __RTEMS_MAJOR__. Remove support for
command line configurable options (--rtems-option).
Rename internal define RTEMS_VERSION_VC_KEY to
RTEMS_VERSION_CONTROL_KEY.
By default, allocate the IDLE task storage areas from the RTEMS Workspace.
This avoids having to estimate the thread-local storage size in the default
configuration.
Add the application configuration option CONFIGURE_IDLE_TASK_STORAGE_SIZE to
request a static allocation of the task storage area for IDLE tasks.
Update #3835.
Update #4524.
Add the INTERNAL_ERROR_IDLE_THREAD_CREATE_FAILED fatal error in case the
creation of an idle thread fails. This may happen due to a failing create
extension provided by the application.
Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPT as the fatal source for
spurious interrupts. Use the interrupt vector number of the spurious
interrupt for the fatal code.
Update #3269.
Make the initialization of the per-CPU data optional.
Change license to BSD-2-Clause according to file history and
re-licensing agreement.
Update #3053.
Use the right system initialization step for the stack allocator
initialization. Do the stack allocator initialization before the
workspace initialization so that _Memory_Allocate() can be used to get
memory for the allocator.
The maximum frequency is UINT32_MAX. Converted to a uint64_t variable
it can be shifted by 32. The addition does not overflow since bin_per_s
- 1 is UINT32_MAX.
Rename Classic API top-level group from Classic to RTEMSImplClassic.
Use RTEMSImplClassic as a prefix for the subgroups. Change the group
names to be in line with the API group names. Use common phrases for
the group brief descriptions.
Update #3706.
In order to better support applications which use the new
rtems_task_construct() directive add the
CONFIGURE_INIT_TASK_CONSTURCT_STORAGE_SIZE configuration option. If
this option is specified, then the Classic API initialization task is
constructed with rtems_task_construct().
Update #4181.
Add this application configuration option. This configuration option can be
used to reserve space for the dynamic linking of modules with thread-local
storage objects.
Add RTEMS_TASK_STORAGE_ALIGNMENT to define the minium alignment of a
thread-local storage size.
Update #4074.
Simplify object name to identifier directives. Using
_RTEMS_Name_to_id() to implement the directives enables a tail call
optimization.
Change license to BSD-2-Clause according to file history.
Update #3053.
The IO library used a POSIX key to store an optional POSIX user
environment pointer. This pulled in the POSIX keys support in every
application configuration. Add a user environment pointer to the thread
control block (TCB) instead. Applications which do not need the POSIX
user environment will just get an overhead of one pointer per thread.
Close#3882.
Use a dedicate system initialization step to zero the memory used for
the workspace and C program heap.
This avoids dead code in case CONFIGURE_ZERO_WORKSPACE_AUTOMATICALLY is
not configured.
Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST
to allow applications and support functions to place system
initialization handlers behind the standard handlers.
Update #3838.
The work area initialization was done by the BSP through
bsp_work_area_initialize(). This approach predated the system
initialization through the system initialization linker set. The
workspace and C program heap were unconditionally initialized. The aim
is to support RTEMS application configurations which do not need the
workspace and C program heap. In these configurations, the workspace
and C prgram heap should not get initialized.
Change all bsp_work_area_initialize() to implement _Memory_Get()
instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and
malloc() heap initialization into separate system initialization steps.
This makes it also easier to test the individual initialization steps.
This change adds a dependency to _Heap_Extend() to all BSPs. This
dependency will be removed in a follow up change.
Update #3838.
