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 := sh4-linux-`
			`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.

Make STANDALONE_LOAD_ADDR configurable per board Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

push LOAD_ADDR out to arch mk files Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org> 2009-09-04 03:12:47 +00:00			`ifeq ($(CPU),sh2)`

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.
