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>
2016-03-17x86: Move common CPU code to its own placeSimon Glass
Some of the Intel CPU code is common to several Intel CPUs. Move it into a common location along with required declarations. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-03-17x86: Add the root-complex block to common intel registersSimon Glass
This is similar to MCH in that it is used in various drivers. Add it to the common header. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2016-03-17x86: Create a common header for Intel register accessSimon Glass
There are several blocks of registers that are accessed from all over the code on Intel CPUs. These don't currently have their own driver and it is not clear whether having a driver makes sense. An example is the Memory Controller Hub (MCH). We map it to a known location on some Intel chips (mostly those without FSP - Firmware Support Package). Add a new header file for these registers, and move MCH into it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
