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.

microblaze: cache: introduce cpuinfo structure Introduce a minimal cpuinfo structure to hold cache related info. The instruction/data cache size and cache line size are initialized early in the boot to default Kconfig values. They will be overwritten with data from PVR/dtb if the microblaze UCLASS_CPU driver is enabled. The cpuinfo struct was placed in global_data to allow the microblaze UCLASS_CPU driver to also run before relocation (initialized global data should be read-only before relocation). gd_cpuinfo() helper macro was added to avoid volatile "-Wdiscarded-qualifiers" warnings when using the pointer directly.

microblaze: Add support for run time relocation Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing issues with function pointer arrays which need to be updated manually after relocation. Building code with -fPIC and linking with -pic will remove this limitation and there is no longer need to run manual update. By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC code will be compiled for full relocation. The patch does couple of things which are connected to each other. - Define STATIC_RELA dependency to call relocate-rela to fill sections. - REMAKE_ELF was already enabled but u-boot file can't be used because sections are empty. relocate-rela will fill them and output file is u-boot.elf which should be used. - Add support for full relocation (u-boot.elf) - Add support for early relocation when u-boot.bin is loaded to different address then CONFIG_SYS_TEXT_BASE - Add rela.dyn and dynsym sections Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original size (550kB to 608kB).
