734208a49b bsp/shared/atomics: New directory 
Provide missing GCC atomics helpers as part of BSPs where GCC
does not know how to provide it since the CPU's ISA has no
atomic instructions. The implementation provided in
bsps/shared/atomics/__atomic_test_and_set.c should work
on any single core CPU.

The BSPs that need thie function tend to have older cores. This
is the list of BSPs:

arm - csb336, csb337, csb637, edb7312, gumstix, kit637_v6, lpc24xx_ea,
  lpc24xx_ncs_ram, lpc24xx_ncs_rom_ext, lpc24xx_ncs_rom_int,
  lpc24xx_plx800_ram, lpc24xx_plx800_rom_int, lpc32xx_mzx,
  lpc32xx_mzx_stage_1, lpc32xx_mzx_stage_2, lpc32xx_phycore,
  rtl22xx, rtl22xx_t, smdk2410
m68k - av5282, mcf5329
mips - jmr3904
moxie - moxiesim
nios2 - nios2_iss
riscv - grv32i, grv32im, niosvc10lp, noel32im, rv32i, rv32im,
sparc - ut699

002c6067ba bsps: Add fatal source/code to bsp_reset() 
Mark bsp_reset() as no-return.  Use default BSP fatal handler in lm32 and m68k

f20078acea build: Use enabled by for defaults 
Merge the "default" and "default-by-variant" attributes.  Use an
"enabled-by" expression to select the default value based on the enabled
set.  This makes it possible to select default values depending on other
options.  For example you could choose memory settings based on whether
RTEMS_SMP is enabled or disabled.

The change was tested by comparing the output of

  ./waf bspdefaults

before and after the change.

4e530464b0 bsps: Default to CPU counter benchmark timer 
Most BSPs which used the stubbed benachmark timer provide a CPU counter.
All BSPs provide at least a stub CPU counter.  Simply use the benchmark
timer implementation using the CPU counter.
