SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

PowerPC: Move -fPIC flag to common place

2011-04-11T19:36:41Z

The -fPIC flag belongs with -mrelocatable, move it there. Also change -fPIC to -fpic as this produces smaller binaries. However, currently -mrelocatable promotes -fpic to -fPIC, a fix for this is in upcoming gcc 4.6 or you can apply this small patch to gcc: diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index 8da8410..e4b8280 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -227,7 +227,8 @@ do { \ } \ \ else if (TARGET_RELOCATABLE) \ - flag_pic = 2; \ + if (!flag_pic) \ + flag_pic = 2; \ } while (0) #ifndef RS6000_BI_ARCH -- Signed-off-by: Joakim Tjernlund

arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work

2010-11-26T21:08:19Z

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.
