2014-03-07kbuild, blackfin: Add CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEEDMasahiro Yamada
Many (but not all) of Blackfin boards give -O2 option to compile under lib/ directory. That means lib/ should be speed-optimized, whereas other parts should be size-optimized. We want to keep the same behavior, but do not want to parse board/*/config.mk again and again. We've got no choice but to invent a new method. CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED, if it is enabled, gives -O2 flag only for building under lib/ directory. Dirty codes which I had marked as "FIX ME" in board/${BOARD}/config.mk have been deleted. Instead, CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED has been defined in include/configs/${BOARD}.h. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Sonic Zhang <sonic.zhang@analog.com>
2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2011-06-03Blackfin: boards: build zlib dir with -O2Mike Frysinger
Now that the zlib code has been relocated to a dedicated subdir, make sure we still build it with -O2 for boards that want speed over size. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-08Blackfin: move CONFIG_BFIN_CPU back to board config.hMike Frysinger
This is a revert of 821ad16fa9900c as Wolfgang doesn't like the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-08Blackfin: unify bootmode based LDR_FLAGS setupMike Frysinger
Unify this convention for all Blackfin boards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-04-08Blackfin: drop CONFIG_SYS_TEXT_BASE from boardsMike Frysinger
We don't want/use this value for Blackfin boards, so punt it and have the common code error out when people try to use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

2010-10-02Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger
The CONFIG_BFIN_CPU option is largely used in the build system, so move it out of the board config.h and into the board config.mk. It'd be nice to keep everything in the config.h, but the patch to extract that value early was rejected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-04-13Rename lib_generic/ to lib/Peter Tyser
Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-04-13Change directory-specific CFLAGS to use full pathPeter Tyser
Previously, a specific file or directory could be compiled with custom CFLAGS by adding a Makefile variable such as: CFLAGS_dlmalloc.o = <custom flags for common/dlmalloc.c> or CFLAGS_lib = <custom flags for lib directory> This method breaks down once multiple files or directories share the same path. Eg FLAGS_fileA = <custom flags> would incorrectly result in both dir1/fileA.c and dir2/fileA.c being compiled with <custom flags>. This change allows finer grained control which we need once we move lib_$ARCH to arch/$ARCH/lib/ and lib_generic/ to lib/. Without this change all lib/ directories would share the same custom CFLAGS.

2009-06-15Blackfin: enable -O2 in lib_generic/ for ADI/Bluetechnix boardsMike Frysinger
Building the compression code in lib_generic/ with -O2 rather than -Os gives a nice speed boost without too much code size increase. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-06-15Blackfin: unify u-boot linker scriptsMike Frysinger
All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
