+4. jtag_khz sets the maximum speed (or alternatively RCLK). If invoked

+interface/xxx.cfg files are always executed *before* target/xxx.cfg
+files, so any jtag_khz in interface/xxx.cfg will be overridden by
+target/xxx.cfg. jtag_khz in interface/xxx.cfg would then, effectively,
+set the default JTAG speed.

+Note that a target/xxx.cfg file can invoke another target/yyy.cfg file,
