#     powerpc/sysdev: drop simple gpio
#     
#     There is a config item CONFIG_SIMPLE_GPIO which
#     provides simple memory mapped GPIOs specific to powerpc.
#     
#     However, the only platform which selects this option is
#     mpc5200, and this platform doesn't use it.
#     
#     There are three boards calling simple_gpiochip_init(), but
#     as they don't select CONFIG_SIMPLE_GPIO, this is just a nop.
#     
#     Simple_gpio is just redundant with the generic MMIO GPIO
#     driver which can be found in driver/gpio/ and selected via
#     CONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.
