Help Request Fixing Raspberry Pi Warnings

[Joel Sherrill]

Hi

Help would be appreciated in eliminating these two warnings:

log/arm-raspberrypi.log:../../../../../../../../rtems/c/src/lib/libbsp/arm/raspberrypi/irq/irq.c:123:16:
warning: implicit declaration of function 'ffs'
[-Wimplicit-function-declaration]
log/arm-raspberrypi.log:../../../../../../../../rtems/c/src/lib/libbsp/arm/raspberrypi/../../shared/gpio.c:328:35:
warning: array subscript is outside array bounds [-Warray-bounds]

I tinkered with the first but I couldn't find the magic combination of
visibility flags to define.
