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> 11 years ago			`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> 15 years ago

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> 15 years ago
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.
