+
+	* cdl/hal_sparc_leon.cdl: update compiler flags for gcc 4.x
+
+2003-07-18  Nick Garnett  <nickg@balti.calivar.com>
+
+	* cdl/hal_sparc_leon.cdl:
+        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
+        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
+        "default_value" from "calculated". This makes it easier
+        to change these values globally.
+        
+2002-10-19  Jonathan Larmour  <jifl@eCosCentric.com>
+
+	Patch from Jiri Gaisler:
+	* cdl/hal_sparc_leon.cdl: -msoft-float needn't be used in local package
+	since it's defined globally.
+	* include/hal_diag.h: Fix UART TX mask.
+
+2002-03-15  Hugo Tyson  <hmt@redhat.com>
+
+	* cdl/hal_sparc_leon.cdl: Add -msoft-cloat to CYGBLD_GLOBAL_CFLAGS
+	(as well as LDFLAGS) - this gives perfect test coverage in minimal
+	build with the sim.  NB pro tem the tools are called
+	sparc-rtems-gcc et al, but sparc-elf-gcc et al should be OK.
+
+2002-03-14  Jiri Gaisler  <jiri@gaisler.com>
+
+	* Initial version based on the SPARClite SIM HAL.

+LEON/TSIM Support
+=================
+
+See <http://www.gaisler.com> for information about the TSIM
+simulator and Leon project per se.
+
+The simulator TSIM can be run "as one" with GDB by using the
+script do-gdb-sim in this directory.  The script can be used in
+automated testing systems to run as if it were embedded within
+GDB.  It contains:
+
+----------------------------------------------------------------
+#! /bin/csh
+tsim-leon -nfp -gdb >& /dev/stdout &
+sparc-rtems-gdb -nw -nx $*:q
+----------------------------------------------------------------
+
+which simply runs tsim in background, directing its output to the
+common stdout.
+
+The command to connect to the simulator target will be
+
+        (gdb) target remote localhost:1234
+
+This fully described in the TSIM documentation from
+  (home)        <http://www.gaisler.com/tsim.html>
+  (flyer)       <http://www.gaisler.com/doc/tsim-erc32.pdf>
