Apparently, at some point automake output changed and these were
not updated.

Provide a file per BSP to list tests that do not build for a BSP. This change
removes the BSP_SMALL_MEMORY hack from the code. That hack was a
mistake.
Provide configuration files for each BSP with tests that cannot build.

Sorting removed the variations across different host operating systems
and file systems.

The TLS section symbols had wrong values in case of an empty TLS data
section and a nonempty TLS BSS section.

Add and use _CPU_SMP_Start_processor(). Add and use
_CPU_SMP_Finalize_initialization(). This makes most
_CPU_SMP_Initialize() functions a bit simpler since we can calculate the
minimum value of the count of processors requested by the application
configuration and the count of physically or virtually available
processors in the high-level code.
The CPU port has now the ability to signal a processor start failure.
With the support for clustered/partitioned scheduling the presence of
particular processors can be configured to be optional or mandatory.
There will be a fatal error only in case mandatory processors are not
present.
The CPU port may use a timeout to monitor the start of a processor.

Also signal to compiler that the start variable in lan91cxx_recv is only used when debugging.

This is necessary to add tests that use the cache manager. For example
to get better estimates of worst-case timings.

The 32-bit ABIs for thread-local storage (TLS) and EABI read-only
small-data area have a conflicting register (r2) usage. Use the System
V small-data instead (here r2 is system reserved).

Rename rtems_smp_process_interrupt() into
_SMP_Inter_processor_interrupt_handler(). Delete unused header file
<rtems/bspsmp.h>.

Rename rtems_smp_secondary_cpu_initialize() into
_SMP_Start_multitasking_on_secondary_processor(). Move declaration to
<rtems/score/smpimpl.h>.

Since the per-CPU SMP lock must be acquired and released to send the
message a single interrupt broadcast operations offers no benefits. If
synchronization is required, then a SMP barrier must be used anyway.

Rename bsp_smp_initialize() into _CPU_SMP_Initialize() since every CPU
port must supply this function.

Merge RTEMS_FATAL_SOURCE_BSP_GENERIC and RTEMS_FATAL_SOURCE_BSP_SPECIFIC
into new fatal source RTEMS_FATAL_SOURCE_BSP. This makes it easier to
figure out the code position given a fatal source and code.

Instead of SPRG0 (= special purpose register 272) use the new global
symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask.
The benefit is that it is now possible to disable interrupts without
further run-time initialization in boot_card().
At least on Freescale e500 cores this leads also to a faster execution
since the mfmsr and mfspr instruction require four cycles to complete.
The instructions to load the mask value can execute while the mfmsr is
in progress.

Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals. This can be used for
example to enable profiling of critical low-level functions.
Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.

Rename rtems_internal_error_description() to

rtems_status_text(). Remove previous implementation of
rtems_status_text().
