+ Semihosting is a method for a target to communicate with a host
+ debugger. It uses special instructions which the debugger will trap
+ on and interpret. This allows U-Boot to read/write files, print to
+ the console, and execute arbitrary commands on the host system.
+
+ Enabling this option will add support for reading and writing files
+ on the host system. If you don't have a debugger attached then trying
+ to do this will likely cause U-Boot to hang. Say 'n' if you are unsure.
