SPDX: Convert all of our single license tags to Linux Kernel style 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>

x86: qemu: split qfw command interface and qfw core This patch splits qfw command interface and qfw core function into two files, and introduces a new Kconfig option (CONFIG_QFW) for qfw core. Now when qfw command interface is enabled, it will automatically select qfw core. This patch also makes the ACPI table generation select CONFIG_QFW.

x86: qemu: fix ACPI Kconfig options CONFIG_GENENRATE_ACPI_TABLE controls the generation of ACPI table which uses U-Boot's built-in methods and CONFIG_QEMU_ACPI_TABLE controls whether to load ACPI table from QEMU's fw_cfg interface. But with commit "697ec431469ce0a4c2fc2c02d8685d907491af84 x86: qemu: Drop our own ACPI implementation", there is only one way to support ACPI table for QEMU targets which is the fw_cfg interface. Having two Kconfig options for this purpose is not necessary any more, so this patch consolidates the two. Signed-off-by: Miao Yan <yanmiaobest@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

x86: qemu: Drop our own ACPI implementation Our own ACPI implementation (when CONFIG_QEMU_ACPI_TABLE is not set) does not build anymore after x86 has been fully converted to DM PCI. Instead of trying to fix the build errors, given we now have the ACPI support via QEMU's fw_cfg interface, which is a more reliable way to generate correct ACPI tables than by ourselves, hence drop our own ACPI implementation.

x86: qemu: add the ability to load and link ACPI tables from QEMU This patch adds the ability to load and link ACPI tables provided by QEMU. QEMU tells guests how to load and patch ACPI tables through its fw_cfg interface, by adding a firmware file 'etc/table-loader'. Guests are supposed to parse this file and execute corresponding QEMU commands.

x86: qemu: add a cpu uclass driver for qemu target Add a cpu uclass driver for qemu. Previously, the qemu target gets cpu number from board dts files, which are manually created at compile time. This does not scale when more cpus are assigned to guest as the dts files must be modified as well. This patch adds a cpu uclass driver for qemu targets to directly read online cpu number from firmware.
