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>

* Patch by Daniel Engström, 13 Nov 2002: Add support for i386 architecture and AMD SC520 board * Patch by Pierre Aubert, 12 Nov 2002: Add support for DOS filesystem and booting from DOS floppy disk

#
Add support for a saving build objects in a separate directory. Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

x86: Add new slimbootloader CPU type This slimbootloader CPU type is to enable U-Boot as a payload which runs on top of Slim Bootloader (https://github.com/slimbootloader). The Slim Bootloader is designed with multi-stage architecture for the execution from reset vector to OS booting, and supports QEMU, Apollolake, Whiskeylake and Coffeelake platforms consuming Intel FSP (https://github.com/IntelFsp) for silicon initialization including CAR and memory initialization. The Slim Bootloader generates new HOB (Hand Off Block) which are serial port info, memory map info, performance data info and so on, and passes it to a Payload. U-Boot as a payload will use these HOB information for basic initialization such as serial console.
