This adds the BCM2835 GPIO controller. It currently implements: - The 54 GPIOs as outputs (qemu_irq) - The SD controller selection via alternate function of GPIOs 48-53 Signed-off-by: Clement Deschamps <clement.deschamps@antfield.fr> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1488293711-14195-4-git-send-email-peter.maydell@linaro.org Message-id: 20170224164021.9066-4-clement.deschamps@antfield.fr Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
