Make rtems_initialize_data_structures(),
rtems_initialize_before_drivers() and rtems_initialize_device_drivers()
static. Rename rtems_initialize_start_multitasking() to
rtems_initialize_executive() and call the registered system
initialization handlers in this function. Add system initialization API
available via #include <rtems/sysinit.h>. Update the documentation
accordingly.
This is no functional change, only the method to call the existing
initialization routines changes. Instead of direct function calls a
table of function pointers contained in the new RTEMS system
initialization linker set is used. This table looks like this (the
actual addresses depend on the target).

Update #2408.
Move the storage for the thread queue heads to the threads. Each thread
provides a set of thread queue heads allocated from a dedicated memory
pool. In case a thread blocks on a queue, then it lends its heads to
the queue. In case the thread unblocks, then it takes a free set of
threads from the queue. Since a thread can block on at most one queue
this works. This mechanism is used in FreeBSD. The motivation for this
change is to reduce the memory demands of the synchronization objects.
On a 32-bit uni-processor configuration the Thread_queue_Control size is
now 8 bytes, compared to 64 bytes in RTEMS 4.10 (other changes reduced
the size as well).
Deprecate Classic API Notepads. Mark task_set/get_note() with
the deprecated attribute, and also mark the notepads field.
Replace disable with enable option for notepads in confdefs.h,
and make notepads disabled by default. The previous option
CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS is now unused and
will emit a compile-time warning. A new option
CONFIGURE_ENABLE_CLASSIC_API_NOTEPADS is available to turn
on notepads, but it also will emit a compile-time warning
to indicate that notepads are deprecated.
Closes#2265
Remove miniIMFS. Statically initialize the root IMFS.
Add configuration options to disable individual
features of the root IMFS, e.g.
o CONFIGURE_IMFS_DISABLE_CHOWN,
o CONFIGURE_IMFS_DISABLE_FCHMOD,
o CONFIGURE_IMFS_DISABLE_LINK,
o CONFIGURE_IMFS_DISABLE_MKNOD,
o CONFIGURE_IMFS_DISABLE_MOUNT,
o CONFIGURE_IMFS_DISABLE_READLINK,
o CONFIGURE_IMFS_DISABLE_RENAME,
o CONFIGURE_IMFS_DISABLE_RMNOD,
o CONFIGURE_IMFS_DISABLE_SYMLINK,
o CONFIGURE_IMFS_DISABLE_UNMOUNT, and
o CONFIGURE_IMFS_DISABLE_UTIME.
This change starts with removing the effectively empty file
timerdrv.h. The prototypes for benchmark_timer_XXX() were in
btimer.h which was not universally used. Thus every use of
timerdrv.h had to be changed to btimer.h. Then the prototypes
for benchmark_timer_read() had to be adjusted to return
benchmark_timer_t rather than int or uint32_t.
I took this opportunity to also correct the file headers to
separate the copyright from the file description comments which
is needed to ensure the copyright isn't propagated into Doxygen
output.
Simplify _RBTree_Insert() and _RBTree_Extract(). Remove more
superfluous NULL pointer checks. Change _RBTree_Is_root() to use only
the node. Add parent parameter to _RBTree_Sibling(). Delete
_RBTree_Grandparent() and _RBTree_Parent_sibling().
Only use the parent pointer, since this pointer is never NULL for nodes
which are part of a tree.
Rename functions from *_off_rbtree() to *_off_tree().
Remove compare function and is unique indicator from the control
structure. Rename RBTree_Compare_function to RBTree_Compare. Rename
rtems_rbtree_compare_function to rtems_rbtree_compare. Provide C++
compatible initializers. Add compare function and is unique indicator
to _RBTree_Find(), _RBTree_Insert(), rtems_rbtree_find() and
rtems_rbtree_insert(). Remove _RBTree_Is_unique() and
rtems_rbtree_is_unique(). Remove compare function and is unique
indicator from _RBTree_Initialize_empty() and
rtems_rbtree_initialize_empty().
Use the PTHREAD mutexes and condition variables if available. This
helps on SMP configurations to avoid the home grown condition variables
via disabled preemption.
