Add a stack allocator hook specifically for allocation of IDLE thread stacks.
This allows the user to decide if IDLE thread stacks are statically allocated
or handled by the same custom allocator mechanism as other thread stacks.
Closes#4524.
ARM's GICv2 is configurable and its attributes vary between
implementations including omission of specific interrupts. This allows
BSPs to accomodate those varying implementations with customized
attribute sets.
If SMP support is enabled and the system has exactly one processor, then
it may use an uniprocessor scheduler. The ask for help, reconsider help
request, and withdraw node operations can be NULL in this case, since
they are only used if a thread has at least one helping scheduler node.
At least two schedulers are required to get a helping node and each
scheduler involved must own at least one processor. This is not
possible on a system with exactly one processor.
The uniprocessor schedulers do not support systems with more than more
processors. So they rivially support thread pinning and thus the
SMP_FATAL_SCHEDULER_PIN_OR_UNPIN_NOT_SUPPORTED cannot happen.
Add a second default implementation for SMP schedulers which do not
support thread pinning.

Certain files related to the Zynq BSP's I2C driver are useable by the ZynqMP BSP as well.
Moved these files to shared directory in anticipation of I2C support for ZynqMP.
Split up rbtreenext.c since only _RBTree_Minimum() is used by the operating
system core services (thread queues and the EDF scheduler).

Update #3053.
Move the TOD validation to the callers of _TOD_Set(). This avoids dead code in
case only rtems_clock_set() is used in an application because rtems_clock_set()
always calls _TOD_Set() with a valid time of day.
The _Thread_Dispatch() function was customized over time and now the
work is done by _Thread_Do_dispatch() and specialized wrappers. The
plain _Thread_Dispatch() is now only used in some CPU ports. Move it to
a separate file to avoid dead code in the general.

Update #3053.
Add rtems_interrupt_entry_remove(). Split up irq-generic.c into several files.
In particular, place all functions which use dynamic memory into their own
file.
Add optional macros to let the BSP customize the vector installation after
installing the first entry and the vector removal before removing the last
entry:
* bsp_interrupt_vector_install()
* bsp_interrupt_vector_remove()
Use these new customization options in the m68k/genmcf548x BSP so re-use the
generic interrupt controller support.
Update #3269.
Add rtems_interrupt_raise_on() and rtems_interrupt_clear().
Add a default implementation which just returns RTEMS_UNSATISFIED for
valid parameters.
Update #3269.
When compiling the lwIP port for the TMS570, there
were issues with the BSP. Headers are expected in a folder
named ti_herc which did not exist. This fixes the issue.
Furthermore, there were multiple warnings about define redefinitions.
This was fixed as well.
These patches were submitted a few months ago, but it was found out
that the default-by-family: [] were missing in the GPIO .yml lines.
This was fixed in this patch.
This patch accounts for different pins for the ETH peripheral
on STM32H7 devices. For example, the Nucleo H743ZI has slightly
different pins than other STM32H7 boards.
Calling the memory FLASH and EXTRAM instead of FLEXSPI and SDRAM makes
it simpler to support other types of external RAM. This patch also
removes some of the calculations and improves names and documentation to
avoid pitfalls. It removes a unnecessary memory definition.
Update #4180
