ARM: Add a new arch + board for QEMU's 'virt' machine This board builds an U-Boot binary that is bootable with QEMU's 'virt' machine on ARM. The minimal QEMU command line is: qemu-system-arm -machine virt,highmem=off -bios u-boot.bin (Note that the 'highmem=off' parameter to the 'virt' machine is required for PCI to work in U-Boot.) This command line enables the following: - u-boot.bin loaded and executing in the emulated flash at address 0x0 - A generated device tree blob placed at the start of RAM - A freely configurable amount of RAM, described by the DTB - A PL011 serial port, discoverable via the DTB - An ARMv7 architected timer - PSCI for rebooting the system - A generic ECAM-based PCI host controller, discoverable via the DTB Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus. The following ones are supported by both U-Boot and Linux: - To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.: -drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0 - To add an Intel E1000 network adapter, pass e.g.: -net nic,model=e1000 -net user - To add an EHCI-compliant USB host controller, pass e.g.: -device usb-ehci,id=ehci - To add a NVMe disk, pass e.g.: -drive if=none,file=disk.img,id=mydisk -device nvme,drive=mydisk,serial=foo Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> 2017-09-20 05:18:07 +09:00			`if ARCH_QEMU`
