am335x starterkit question -1

hi..

i review am335x evm-starterkit gpio-keys driver. 

evm-starterkit has SW1~SW4 and this button is mapped BTN_0~BTN_3 in "board-am335xevm.c" file

i can't understand this mapping. i saw this button's function is MENU, HOME, BACK, SEARCH.

i think BTN_0 code is changed to KEY_MENU,, and BTN_1 is changed to KEY_HOME. etc..

is there any remapping code in "gpio_keys.c" ?
