This adds minimal support for the new Raspberry Pi 4 without the fancy stuff like GENET, PCIe, xHCI, 40 bit DMA and V3D. The RPi 4 is available in 3 different variants (1, 2 and 4 GB RAM), so leave the memory size to zero and let the bootloader take care of it. The DWC2 is still usable as peripheral via the USB-C port. Other differences to the Raspberry Pi 3: - additional GIC 400 Interrupt controller - new thermal IP and HWRNG - additional MMC interface (emmc2) - additional UART, I2C, SPI and PWM interfaces - clock stretching bug in I2C IP has been fixed Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Acked-by: Eric Anholt <eric@anholt.net> Acked-by: Florian Fanelli <f.fainelli@gmail.com>
