    sh: Fix up se7721 GPIOLIB=y build warnings. · 64941d89
    Paul Mundt authored
    Presently the SH7720/21 serial code uses asm/gpio.h to get at the CPU
    GPIO port definitions, but in the case of GPIOLIB=y this also includes
    references to generic GPIOLIB routines that we don't have any function
    declarations for, tripping up on -Werror=implicit-function-declaration
    with newer gcc versions:

    Switch to using the cpu/ version for the port definitions explicitly.
