+# http://www.st.com/spear
+#
+# List of board modifications to enable SRST, as per ST Application Note
+# (FIXME: put reference to AN)
+# - Modifications on the top layer:
+# 1. remove R137 and C57, located near the SMII PHY U18;
+# 2. remove R172 and C75, located near the SMII PHY U19;
+# 3. remove R207 and C90, located near the SMII PHY U20;
+# 4. remove C236, located near the SMII PHY U21;
+# 5. remove U12, located near the JTAG connector;
+# 6. solder together pins 7, 8 and 9 of U12;
+# 7. solder together pins 11, 12, 13, 14, 15, 16, 17 and 18 of U12.
+# - Modifications on the bottom layer:
+# 8. replace reset chip U11 with a STM6315SDW13F;
+# 9. add 0 ohm resistor R329. It is located close to JTAG connector.
