This PR consolidates the work we've done to support the new Raspberry Pi 4 board. It also includes commits from https://github.com/mbgg/u-boot.git (credits to Matthias Brugger).
Andrei Gherzan (13): dts: Create a dtsi for BCM2835/6/7 specific configuration dts: Add initial support for bcm2838 arm: mach-bcm283x: Define configs for RaspberryPi 4 arm: mach-bcm283x: Define mbox address for BCM2838 rpi: Add rpi_model entry for RaspberryPi 4 dt-bindings: Define BCM2838_CLOCK_EMMC2 needed for RaspberryPi 4 arm: bcm283x: Include definition for additional emmc clock arm: bcm283x: Define device base addresses for bcm2835 config: rpi4: Add defconfig for rpi4-32 dts: bcm2838-rpi-4-b: Use the emmc2 interface for sdhci rpi: Add memory map for bcm2838 configs: rpi4: Remove DWC2 and USB_ETHER configs dts: bcm2838-rpi-4-b: Use the emmc2/2811 compatible string for SDHCI
Fabian Vogt (2): bcm2835 video: Bail out early if querying video information fails bcm283x mbox: Correctly wait for space to send
Matthias Brugger (1): mmc: bcm2835_sdhci: Add support for bcm2711 device
