cb2afd2eaa bsps/shared: Add PSCI-based bspreset implementation 
This adds a bsp_reset implementation based on the ARM PSCI
specification often present in ARMv8 systems.

02c9eb8567 bsps/fdt: Make sure data is cache aligned 
The cache of the fdt blob is flushed after copy. Therefore it should be
aligned.

eea21eaca1 bsps: Rework work area initialization 
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.

c331bdc777 record: Allow tracing of ISR disable/enable 
Directly use the CPU port API in boot_card() to allow tracing of the
higher level interrupt disable/enable routines, e.g.
_ISR_Local_disable() and _ISR_Local_enable().  Currently, there is no
configuration option to enable this.  Below is a patch.  It may be used
to investigate some nasty low level bugs in the system.

Update #3665.

212663bede bsps: Adjust architecture Doxygen groups 
- Use CamelCase as it is not used in our C code.  Enables simple search and
   replace.

 - Prefix with "RTEMS" to aid deployment and integration.  It aids
   searching and sorting.
