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>

If global NVS says internal UART is not enabled, hide it in the ASL code so that OS won't see it.

2016-05-30x86: acpi: Create a common irqlinks ASL fileBin Meng
Move the irqlinks.asl file currently in the BayTrail directory to a common place to be shared among all x86 platforms. As the PIRQ routing control programming interface is common to Intel chipsets, leave the common part in the common file, and move the platform specific part to the platform files.

2016-05-23x86: baytrail: Add internal UART ASL descriptionBin Meng
BayTrail integrates an internal ns15550 compatible UART (PNP0501). Its IRQ is hardwired to IRQ3 in old revision chipset, but in newer revision one IRQ4 is being used for ISA compatibility. Handle this correctly in the ASL file. Linux does not need this ASL, but Windows need this to correctly discover a COM port existing in the system so that Windows can show it in the 'Device Manager' window, and expose this COM port to any terminal emulation application.

2016-05-23x86: baytrail: Add platform ASL filesBin Meng
This adds basic BayTrail platform ASL files. They are intended to be included in dsdt.asl of any board that is based on this platform. Note: ACPI mode support for GPIO/LPSS/SCC/LPE are not supported for now. They will be added in the future. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
