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>

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.

kbuild: Descend into SOC directory from CPU directory Some CPUs of some architectures have SOC directories. At present, the build system directly descends into SOC directories from the top Makefile, but it should generally descend into each directory from its parent directory.

# some files can only build in ARM or THUMB2, not THUMB1
arm: Migrate SYS_THUMB_BUILD to Kconfig, introduce SPL_SYS_THUMB_BUILD Today, we have cases where we wish to build all of U-Boot in Thumb2 mode for various reasons. We also have cases where we only build SPL in Thumb2 mode due to size constraints and wish to build the rest of the system in ARM mode. So in this migration we introduce a new symbol as well, SPL_SYS_THUMB_BUILD to control if we build everything or just SPL (or in theory, just U-Boot) in Thumb2 mode.
