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: Generate a valid ACPI table Implement write_acpi_table() to create a minimal working ACPI table. This includes writing FACS, XSDT, RSDP, FADT, MCFG, MADT, DSDT & SSDT ACPI table entries. Use a Kconfig option GENERATE_ACPI_TABLE to tell U-Boot whether we need actually write the APCI table just like we did for PIRQ routing, MP table and SFI tables. With ACPI table existence, linux kernel gets control of power management, thermal management, configuration management and monitoring in hardware.
