125* Board must register gpiochips.
126*(2) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=n:
127* A gpiochip for the 75 GPIOs is registered.
128*
129*(3) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=y:
130* the boards' gpio.h must provide the linux gpio wrapper functions,
131*
132*(4) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=n:
133* inlinable gpio functions are provided which enable access to the
134* Au1300 gpios only by using the numbers straight out of the data-
135* sheets.
136
137* Cases 1 and 3 are intended for boards which want to provide their own
138* GPIO namespace and -operations (i.e. for example you have 8 GPIOs
139* which are in part provided by spare Au1300 GPIO pins and in part by
140* an external FPGA but you still want them to be accssible in linux
141* as gpio0-7. The board can of course use the alchemy_gpioX_* functions
142* as required).
