40#  CONSOLE_USE_INTERRUPTS (leon_bsp)
41#     The erc32 console driver can operate in either polled or interrupt mode.
42#     Under the simulator (especially when FAST_UART is defined), polled seems
43#     to operate better.  It is common for a task to print a line (like the
44#     end of test message) and then exit.  In this case, the program returns
45#     control to the simulator command line before the program has even queued
46#     the output to the uart.  Thus sis has no chance of getting the data out.
47#
48#  SIMSPARC_FAST_IDLE (leon_bsp)
49#     If defined, speed up the clock ticks while the idle task is running so
50#     time spent in the idle task is minimized.  This significantly reduces
51#     the wall time required to execute the RTEMS test suites.
52#
53#  CPU_U32_FIX (all)
54#     Needed to align received TCP/IP packets since SPARC does not
55#     support unaligned memory access.
