+# Configuration for the ST SPEAr320 Evaluation board
+# EVAL_SPEAr320CPU Rev. 2.0, modified to enable SRST on JTAG connector
+# http://www.st.com/spear
+#
+# List of board modifications to enable SRST, as reported in
+# ST Application Note (FIXME: add reference).
+# - Modifications on the bottom layer:
+#    1. replace reset chip U7 with a STM6315SDW13F;
+#    2. add 0 ohm resistor R45. It is located close to JTAG connector.
+#    3. add a 10K ohm pull-up resistor on the reset wire named as
+#       POWERGOOD in the schematic.
+#
+# The easier way to do modification 3, is to use a resistor in package
+# 0603 or 0402 and solder it between R15 and R45:
+# - one pad soldered with the pad of R15 connected to 3.3V (this
+#   is the pad of R15 closer to R45)
+# - the other pad soldered with the nearest pad of R45.
