[U-Boot] [PATCH v3 0/36] Switch over to real Kbuild
by Masahiro Yamada 27 Dec '13

27 Dec '13

We switched to Kbuild style makefiles at v2014.01-rc1 release. With that modification, we can write makefiles simpler. But it is NOT real Kbuild. As the next step, this series imports (+ adjusts) build scripts from Linux Kernel under scripts/ directory. By applying this series, we can get more advantages: - short log - perfect dependency tracking - preparation to the next step: Kconfig - other things... Kbuild without Kconfig ---------------------- First of all, to make things clearer, let me explain the difference between "Kbuild" and "Kconfig". They are, I think, sometimes confusing. Kbuild - build system used for Linux Kernel. Some features of Kbuild are: (a) We can describe makefiles simply. Just add objects to "obj-y" like this: obj-$(CONFIG_FOO) += foo.o (b) We can describe directory descending nicely. Add directories with a slash to "obj-y" like this: obj-$(CONFIG_BAR) += bar/ (c) Short log like follows: CC common/foo.o CC common/bar.o LD common/built-in.o (d) Perfect dependency tracking I think this is the biggest advantage. To be honest, the dependency tracing of U-Boot build system was not reliable. Kconfig - A tool to manage CONFIG macros. We can handle the dependency among CONFIG macros. Kconfig allows us to modify CONFIG settings easily by "make config". GUI interface are also available by "make menuconfig" All defined CONFIG macros are stored into ".config" file I think most of U-boot developers are already familiar with above. (In most cases, they are Linux Kernel developers too.) I definitely want to port both of these, but I want to do them separately: Kbuild first. (If we do Kbuild and Kconfig at the same time, it might be messed up.) So, I want to do "Kbuild without Kconfig" in this series. The conventional tool (mkconfig + boards.cfg file) is used for board configuration. Prerequisite ------------ You need to apply the followings beforehand to use this series. [1] sandbox: Use system headers first for sandbox's os.c in a different way http://patchwork.ozlabs.org/patch/294233/ How to Build ? -------------- We can build the same as before. Do board configuraton first and then run "make". $ make omap4_panda_config Configuring for omap4_panda board... $ make CROSS_COMPILE=arm-linux-gnueabi- GEN include/autoconf.mk.dep GEN include/autoconf.mk CC lib/asm-offsets.s GEN include/generated/generic-asm-offsets.h CC arch/arm/cpu/armv7/omap4/asm-offsets.s GEN include/generated/asm-offsets.h HOSTCC scripts/basic/fixdep ... You will find a difference at a glance, short log If you need detail log message, please add "V=1". (You can also use "V=2") Please note we can no longer use $ make omap4_panda CROSS_COMPILE=arm-linux-gnueabi- to do board configuration and "make" at the same time. Instead, we can use Kbuild-ish way for that purpose: $ make omap4_panda_config all CROSS_COMPILE=arm-linux-gnuabi- This series keeps the other features: - Support out-of-tree build You can use "O=<dir_name>" like this $ mkdir build_dir $ make omap4_panda_config all O=build_dir CROSS_COMPILE=arm-linux-gnueabi- - Works with parallel make option Add "-j" option for this. Compiling will get faster. - Of cource, SPL, TPL build are supported (nand_spl also works. But "nand_spl" is obsolete and we should switch to "spl". Until when should we continue to maintain nand_spl?) - Breaks no boards (except some boards which are already broken) I built all target boards to prove correctness of this series at least for compile test. My Next Plan ------------ - Import Kconfig Use "make config", "make menuconfig", "make defconfig", etc. in U-Boot. - More refactoring Some parts of makefiles are still dirty. I want to refactor more makefiles in follow-up patches. - Use "obj-m" for standalone program?? Loadable module?? I have not deceided about this yet. Known Problems -------------- - ".*.su" files at the top directory After build, you will notice ".*.su" files at the top directory. $ ls -a . .20193.su CREDITS api disk include scripts u-boot-nand.bin u-boot.srec .. .20198.su Licenses arch doc lib snapshot.commit u-boot-pad.img .18993.su .20203.su MAKEALL board drivers mkconfig spl u-boot.bin .18998.su .checkpatch.conf Makefile boards.cfg dts nand_spl test u-boot.ldr .19037.su .git README common examples net tools u-boot.lds .19042.su .gitignore System.map config.mk fs post u-boot u-boot.map These files ".<process_number>.su" are created when -fstack-usage is given to $(call cc-option, ...) I will fix this problem correctly lator. - I marked dirty parts with "FIX ME". In some board-specific config.mk files. # FIX ME ifneq ($(filter lib lib/lzma lib/zlib, $(obj)),) ccflags-y := -O2 endif In the top Makefile # FIX ME cpp_flags := $(KBUILD_CPPFLAGS) $(CPPFLAGS) $(UBOOTINCLUDE) $(NOSTDINC_FLAGS) c_flags := $(KBUILD_CFLAGS) $(cpp_flags) I will re-write them more nicely after other parts are prepared. Changes for v3: - Rebase on the current u-boot/master - Add a new patch at the tail: 36/36 "board: sandburst: delete FORCEBUILD" Changes for v2: - At version 1, nand_spl boards got broken at 12 and fixed at 14. Fix this problem - At version 1, sandbox got broken at 17 and fixed at 21.

[U-Boot] [PATCH] bootm: Reinstate special case for standalone images
by Simon Glass 27 Dec '13

27 Dec '13

For standalone images, bootm had a special case where the OS boot function was NULL but did actually exist. It was just called manually. This was removed by commit 35fc84fa which checks for the non-existence of this function before the special case is examined. There is no obvious reason why standalone is handled with a special case. Adjust the code so that standalone has a normal OS boot function. We still need a special case for when the function returns, but at least we can avoid the main problem. This is intended to fix the reported: ERROR: booting os 'U-Boot' (17) is not supported but needs testing.
