Remove unused licenses, add the SLAC license template, and rearrange the
order of the licenses to emphasize the 2-BSD and other preferred
licenses earlier.
Fixes#5200.
This commit adds support for CTU CAN FD controller. The controller
can be initialized from BSP by ctucanfd_initialize() function call.
It also implements the dynamic redistribution of hardware transmission
buffers to CAN stack priority classes in order to avoid possible
priority inversion.

This commit adds a support for a simple virtual CAN controller. This
controller can be used to test CAN stack functions and serves as an
inspiration for further controller implementations.

This adds support for common full-featured CAN/CAN FD stack to RTEMS.
The API is provided in form the form of the POSIX character driver with
each CAN controller (chip) registered as node into “/dev”
namespace.
The stack utilizes FIFO queues (also called edges) organized
into oriented edges between controller side and application side.
Edges, responsible for message transfers from application to controller
and vice versa, can have different priorities and function as priority
classes.
The stack provides run time configuration options to create new
queues with desired priority, direction and filter, making it
suitable for various applications requirements. There is also a
possibility to configure controller’s characteristics (bit rate,
mode, chip specific ioctl calls). Both blocking and nonblocking mode
is supported.

When compilation and linking are performed separately, some platforms
(i.e. RISC-V) may require that ABI flags are provided during the linking
step as well as the compilation step.
This commit aligns trampolines for THUMB and ARM instructions
(CALL/JUMP24 and THM_JUMP24/THM_PC22).
According to the ARM technical reference in section "Register-relative
and PC-relative expressions":
In Thumb code:
- For B, BL, CBNZ, and CBZ instructions, the value of the PC is the
address of the current instruction plus 4 bytes.
- For all other instructions that use labels, the value of the PC is
the address of the current instruction plus 4 bytes, with bit[1]
of the result cleared to 0 to make it word-aligned.
The RTEMS_CAPTURE_OVERFLOW is an overflow flag for each CPU, and its
value is the same as RTEMS_CAPTURE_INIT. Executing rtems_capture_flush
will set the RTEMS_CAPTURE_INIT flag to 0 in the global flags.
The POSIX sporadic server may temporarily remove the real priority of a
thread. Check that the priority node is active before the change is
propagated.
Update #5168.
Previously the system event used by lio_listio was manually added to
event.h and not using rtems-central. This patch corrects that and renames
the event to make it clearer.
Some related dead code has also been removed.
This moves the management console implementation into its own file so
that BSPs which do not need it do not carry the code around with them.
Closes#5120
This adds generic JFFS2 interworking code that allows JFFS2 to be used
on top of any flashdev backend. It currently only supports NOR flashdev
backends.
Commit 3d782180ea changed the reported Git
hash to short. Change this back to the normal Git hash. Existing
support code may rely on this. The short hash is generated based on the
current repository state. The reported hash should be useful also for
future states of the repository. If Git changes the hash algorithm in
the future, then the hash length may be used as an indicator for the
hash algorithm. With a variable hash length this is more difficult.
Simplify expression.
Update #5037.
Accesses to the L2C registers performed by the L2C driver are now
serialized with spin locks. This avoids concurrent access to the L2C
registers by multiple processors. Proposed by GRLIB-TN-0021.
Update #4925.
