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> 2018-05-06 21:58:06 +00:00			`# SPDX-License-Identifier: GPL-2.0+`

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> 2014-02-28 05:33:30 +00:00			`ifeq ($(CROSS_COMPILE),)`
			`CROSS_COMPILE := nios2-elf-`
			`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.

nios2: Make STANDALONE_LOAD_ADDR configurable per board Follow commit 8ae86b76c648d8bef97241c78e2fddb1c4f164d3 which changed the variable name.

push LOAD_ADDR out to arch mk files Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org> 2009-09-04 03:12:47 +00:00

nios2: fix r15 issue for gcc4 The "-ffixed-r15" option doesn't work well for gcc4. Since we don't use gp for small data with option "-G0", we can use gp as global data pointer. This allows compiler to use r15. It is necessary for gcc4 to work properly.

nios2: Move individual board linker scripts to common script in cpu tree. Signed-off-by: Scott McNutt <smcnutt@psyent.com> 2010-04-16 20:12:39 +00:00
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.
