 To use semi-hosting for a replacement UART:
-- Add lib/semihosting/semihosting.c to the Makefile sources.
+- Add shared/runtime/semihosting_arm.c to the Makefile sources.
 - Call mp_semihosting_init() in main(), around the time UART is initialized.
 - Replace mp_hal_stdin_rx_chr and similar in mphalport.c with the semihosting equivalent.
-- Include lib/semihosting/semihosting.h in the relevant files.
+- Include shared/runtime/semihosting_arm.h in the relevant files.
 
 Then make sure the debugger is attached and enables semihosting.  In OpenOCD this is
 done with ARM semihosting enable followed by reset.  The terminal will need further
