Hello Alexandre,

Using the latest 3.19 kernel, the bcm63xx GPIO code under
arch/mips/bcm63xx/gpio.c is unable to register the gpio chip via
gpiochip_add(), as it returns -ENOMEM. The kcalloc call for the gpio_desc
array fails, as during prom code, it is too early for the kmalloc to work.

It looks like the issue is caused by your patch: "gpio: remove gpio_descs
global array"

Could you please advise on how to fix/workaround that ? (ideally while keeping
the possibility to invoke the gpiolib code from the setup/prom code).

Regards,
