Align Raspberry Pi DMA interrupts with Linux DTS There is nothing in the specs on DMA engine interrupt lines: it should have been in the "BCM2835 ARM Peripherals" datasheet but the appropriate "ARM peripherals interrupt table" (p.113) is nearly empty. All Raspberry Pi models 1-3 (based on bcm2835) have Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25): /* dma channel 11-14 share one irq */ This information is repeated in the driver code (drivers/dma/bcm2835-dma.c +1344): /* * in case of channel >= 11 * use the 11th interrupt and that is shared */ In this patch channels 0--10 and 11--14 are handled separately.

target-arm: Implement BCM2835 hardware RNG Recent vanilla Raspberry Pi kernels started to make use of the hardware random number generator in BCM2835 SoC. As a result, those kernels wouldn't work anymore under QEMU but rather just freeze during the boot process. This patch implements a trivial BCM2835 compatible RNG, and adds it as a peripheral to BCM2835 platform, which allows to boot a vanilla Raspberry Pi kernel under Qemu. Changes since v1: * Prevented guest from writing [31..20] bits in rng_status * Removed redundant minimum_version_id_old * Added field entries for the state * Changed realize function to reset Signed-off-by: Marcin Chojnacki <marcinch7@gmail.com> Message-id: 20170210210857.47893-1-marcinch7@gmail.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

Align Raspberry Pi DMA interrupts with Linux DTS There is nothing in the specs on DMA engine interrupt lines: it should have been in the "BCM2835 ARM Peripherals" datasheet but the appropriate "ARM peripherals interrupt table" (p.113) is nearly empty. All Raspberry Pi models 1-3 (based on bcm2835) have Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25): /* dma channel 11-14 share one irq */ This information is repeated in the driver code (drivers/dma/bcm2835-dma.c +1344): /* * in case of channel >= 11 * use the 11th interrupt and that is shared */ In this patch channels 0--10 and 11--14 are handled separately.

target-arm: Implement BCM2835 hardware RNG Recent vanilla Raspberry Pi kernels started to make use of the hardware random number generator in BCM2835 SoC. As a result, those kernels wouldn't work anymore under QEMU but rather just freeze during the boot process. This patch implements a trivial BCM2835 compatible RNG, and adds it as a peripheral to BCM2835 platform, which allows to boot a vanilla Raspberry Pi kernel under Qemu. Changes since v1: * Prevented guest from writing [31..20] bits in rng_status * Removed redundant minimum_version_id_old * Added field entries for the state * Changed realize function to reset Signed-off-by: Marcin Chojnacki <marcinch7@gmail.com> Message-id: 20170210210857.47893-1-marcinch7@gmail.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

bcm2835: add sdhost and gpio controllers This adds the bcm2835_sdhost and bcm2835_gpio to the BCM2835 platform. For supporting the SD controller selection (alternate function of GPIOs 48-53), the bcm2835_gpio now exposes an sdbus. It also has a link to both the sdbus of sdhci and sdhost controllers, and the card is reparented from one bus to another when the alternate function of GPIOs 48-53 is modified.
