if we cut out the friendly port naming, the rest of the code is no longer Blackfin specific. so what i had been thinking of doing at some point was dropping that as a requirement and making it a "nice" feature so it could be moved into common/cmd_gpio.c for everyone to use. so if we rip out that part and just make it something like: ... #ifndef name_to_gpio #define name_to_gpio(name) simple_strtoul(name, NULL, 10) #endif ... ulong pin = name_to_gpio(argv[2]); if (!gpio_is_valid(pin)) goto usage; ... although perhaps in your case, we can just change "if (pin > 15)" to "if (!gpio_is_valid(pin))" and forget about the people who do PF34 on parts that only have PF0..PF15 (they'll instead get like PH4 or whatever). -mike
