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>

arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

kbuild: fix CROSS_COMPILE settings in config.mk The syntax CROSS_COMIPLE ?= <cross_compiler_prefix> does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := <cross_compiler_prefix> endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

ifeq ($(CROSS_COMPILE),)
CROSS_COMPILE := ppc_8xx-
endif
push CROSS_COMPILE out to $(ARCH)_config.mk Each arch should handle setting a proper default CROSS_COMPILE value in their own config.mk file rather than having to maintain a large ugly list in the Makefile. By using conditional assignment, we don't have to worry about the variable already being set (env/cmdline/etc...). The common config.mk file takes care of exporting CROSS_COMPILE already, and while a few variables (toolchain ones) utilize CROSS_COMPILE before including the arch config.mk, they do so with deferred assignment.

Introduce a new linker flag LDFLAGS_FINAL commit 8aba9dceebb14144e07d19593111ee3a999c37fc Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS breaks the usage of --gc-section to build nand_spl. We still need linker option --gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes the --gc-sections to each uboot image. To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

powerpc: add --bss-plt to LDFLAGS With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected) it is necessary to specify --bss-plt to get the final blrl in the _GOT2_TABLE_. Without this the last symbol does not get it's address relocated. For the P2041RDB board this ended up being NetArpWaitTimerStart which caused the ARP packets to timeout immediately.

kconfig / kbuild: Re-sync with Linux 4.19 Align Kconfig and Kbuild logic to Linux 4.19 release with minimal impact on files outside of this scope. Our previous Kconfig sync was done by commit 5972ff077e0f ("kconfig / kbuild: re-sync with Linux 4.18"). In this particular re-sync in order to keep clang support working a number of related changes needed to be pulled in that had been missed previously.

powerpc: change .fixup test to a GCC version test This was introduced by commit 244615197469dd6fe75ae082f38424b97c79aeaf, but it fails in a minimal SPL build where the only thing in arch/powerpc/lib is cache.c, which apparently doesn't generate any fixup records.
