2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-19ARM: qemu-arm: Add support for AArch64Tuomas Tynkkynen
This adds support for '-machine virt' on AArch64. This is rather simple: we just add TARGET_QEMU_ARM_xxBIT to select a few different Kconfig symbols, provide the ARMv8 memory map from the board file and add a new defconfig based on the 32-bit defconfig.

2017-10-06ARM: Add a new arch + board for QEMU's 'virt' machineTuomas Tynkkynen
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>
