The gpio_from_string() call shall parse the incoming GPIO name taken from the command line and return the GPIO number used within U-Boot or return -1 on error.

You mean blackfin specific macro crap? Let's actually drop that and switch over to this one. That was my intention from start.
don't spout this crap. try reading the actual history on the lists for the background on the naming, and then try actually grepping the tree to see that multiple targets implement it.
So ... it was chosen to be compatible with linux gpio api, that's what I understood ... so I grepped the kernel source:
linux-2.6# git grep name_to_gpio drivers/gpio/ linux-2.6# git grep name_to_gpio include/ linux-2.6# git grep gpio_to_name include/ linux-2.6# git grep gpio_to_name drivers/gpio/
Nothing.
the naming convention is inline with the linux naming convention. there is no concept in linux of stringifying a GPIO number. -mike
