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