* kbuild: Rename UIMAGE to MKIMAGEMarek Vasut2014-03-28-1/+1
| | | | | | | | | | | | | | | U-Boot uses the 'mkimage' tool to produce various image types, not only uImage image type. Rename the invocation name from UIMAGE to MKIMAGE. The following command was used to do the replacement: git grep 'quiet_cmd_mkimage.* = UIMAGE' | cut -d : -f 1 | \ xargs -i sed -i "s@\(quiet_cmd_mkimage\)\(.*\) = UIMAGE @\1\2 = MKIMAGE@" {} Signed-off-by: Marek Vasut <marex@denx.de> Cc: Tom Rini <trini@ti.com> Cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* kbuild: improve Kbuild speedMasahiro Yamada2014-03-07-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kbuild brought about many advantages for us but a significant performance regression was reported by Simon Glass. After some discussions and analysis, it turned out its main cause is in $(call cc-option,...). Historically, U-Boot parses all config.mk (arch/*/config.mk and board/*/config.mk) every time descending into subdirectories. That means cc-options are evaluated over and over again. $(call cc-option,...) is useful but costly. So we want to evaluate them only in ./Makefile and spl/Makefile and export compiler flags. This commit changes the build system as follows: - Modify scripts/Makefile.build to not include config.mk Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y, cppflags-y. - Export many variables Going forward, Kbuild will not parse config.mk files when it descends into subdirectories. If we want to set variables in config.mk and use them in subdirectories, they must be exported. This is the list of variables to get exported: PLATFORM_CPPFLAGS CPUDIR BOARDDIR OBJCOPYFLAGS LDFLAGS LDFLAGS_FINAL (used in nand_spl/board/*/*/Makefile) CONFIG_STANDALONE_LOAD_ADDR (used in examples/standalone/Makefile) SYM_PREFIX (used in examples/standalone/Makefile) RELFLAGS (used in examples/standalone/Makefile) - Delete CPPFLAGS This variable has been replaced with PLATFORM_CPPFLAGS - Copy gcclibdir from example/standalone/Makefile to arch/sparc/config.mk The reference in CONFIG_STANDALONE_LOAD_ADDR must be resolved before it is exported.

* kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCCMasahiro Yamada2014-03-07-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the location of include directives of board configuration files. The purpose of this change is: - Slim down $(TOPDIR)/config.mk - Prevent $(TOPDIR)/Makefile from including the same configuration file twice - Do not include include/config.mk multiple times because ARCH, CPU, BOARD, VENDOR, SOC are exported Before this commit: - include/autoconf.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/autoconf.mk twice) - include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk - include/config.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/config.mk twice) After this commit: - include/autoconf.mk is included from $(TOPDIR)/Makefile and $(TOPDIR)/scripts/Makefile.build - include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile and $(TOPDIR)/scripts/Makefile.build - include/config.mk is included from $(TOPDIR)/config.mk and $(TOPDIR)/spl/Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-25/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

* Makefile: prepare for using Kbuild-style MakefileMasahiro Yamada2013-10-31-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every makefile in sub directories has common lines at the top and the bottom. This commit pushes the common parts into script/Makefile.build. Going forward sub-makefiles only need to describe this part: COBJS := ... COBJS += ... SOBJS := ... But using obj-y is preferable to prepare for switching to Kbuild. The conventional (non-Kbuild) Makefile style is still supported. This is achieved by greping the Makefile before entering into it. U-Boot conventional sub makefiles always include some other makefiles. So the build system searches a line beginning with "include" keyword in the makefile in order to distinguish which style it is. If the Makefile include a "include" line, we assume it is a conventional U-Boot style. Otherwise, it is treated as a Kbuild-style makefile. With this tweak, we can switch sub-makefiles from U-Boot style to Kbuild style little by little. obj-y := foo/ syntax (descending into the sub directory) is not supportd yet. It will be implemented in the upcomming commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Simon Glass <sjg@chromium.org> Cc: Tom Rini <trini@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can not be more than 4K. So, the SPL cannot initialize the DDR with the SPD code. This patch introduces TPL to enable a loader stub that is loaded by the code from the SPL. It initializes the DDR with the SPD or other operations. The TPL's size is sizeable, the maximum size is decided by the memory's size that TPL runs. It initializes the DDR through SPD code, and copys final uboot image to DDR. So there are three stage uboot images: * spl_boot, * tpl_boot, * final uboot image Signed-off-by: Ying Zhang <b40530@freescale.com> Acked-by: York Sun <yorksun@freescale.com>
