3647725832 bsps/shared: Add PSCI SMP startup support 
This adds the SMP function that supports spinup of additional CPU cores
using the ARM standard PSCI inteface. This interface is provided by QEMU
as well as ARM Trusted Firmware running in monitor mode (EL3) on ARMv7 and
AArch64 CPUs. This supports activation va SMC or HVC instructions
depending on BSP configuration.

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
