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 avail= able in 3 different variants (1, 2 and 4 GB RAM), so leave the memory size to z= ero and let the bootloader take care of it. 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 Signed-off-by: Stefan Wahren <wahrenst@gmx.net> =2D--

It's an iproc-rng200, so you can either re-use the bcm7211-rng compatible string that was just recently added or you can define a bcm2838-rng if you prefer. -- Florian _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
