+# Sayma AMC is an FPGA board for the µTCA AMC format
+# The board is open hardware (CERN OHL) and the gateware and software
+# running on it are open source (ARTIQ, LGPLv3+).
+#
+# https://github.com/m-labs/sinara/wiki/Sayma
+#
+# It contains a Xilinx Kintex Ultrascale 040 FPGA (xcku040).
+# There is a SCANSTA112SM JTAG router on the board which is configured to
+# automatically add devices to the JTAG svcan chain when they are added.
+# Sayma AMC is usually combined with Sayma RTM (rear transition module)
+# which features an Artix 7 FPGA.
