2014-03-31arm: mxs: Add support for generating signed BootStreamMarek Vasut
This patch adds the groundwork for generating signed BootStream, which can be used by the HAB library in i.MX28. We are adding a new target, u-boot-signed.sb , since the process for generating regular non-signed BootStream is much easier. Moreover, the signed bootstream depends on external _proprietary_ _binary-only_ tool from Freescale called 'cst', which is available only under NDA. To make things even uglier, the CST or HAB mandates a kind-of circular dependency. The problem is, unlike the regular IVT, which is generated by mxsimage, the IVT for signed boot must be generated by hand here due to special demands of the CST. The U-Boot binary (or SPL binary) and IVT are then signed by the CST as a one block. But here is the problem. The size of the entire image (U-Boot, IVT, CST blocks) must be appended at the end of IVT. But the size of the entire image is not known until the CST has finished signing the U-Boot and IVT. We solve this by expecting the CST block to be always 3904B (which it is in case two files, U-Boot and the hand-made IVT, are signed in the CST block).

2014-02-25kbuild: Move linker sciript check to prepare1Masahiro Yamada
Same as the previous commit. Move sanity check to prepare1 target to avoid nasty troubles. Before this commit, LDSCRIPT existence was not checked when it was specified by CONFIG_SYS_LDSCRIPT. Now LDSCRIPT existence is checked for all boards. $(wildcard $(LDSCRIPT)) must point to the linker scripts with absolute path. Otherwise, make will terminate with a false error on out-of-tree build.

2014-02-25kbuild: Fix a false error of generic board supportMasahiro Yamada
Before this commit, make terminated with an error where is shouldn't under some condition. This bug happened when we built a board unsupporting generic board right after building with generic board. For example, the following sequence failed. (harmony uses generic board but microblaze-generic does not support it) $ make harmony_config Configuring for harmony board... $ make CROSS_COMPILE=arm-linux-gnueabi- [ Build succeed ] $ make microblaze-generic_config Configuring for microblaze-generic board... $ make CROSS_COMPILE=microblaze-linux- Makefile:488: *** Your architecture does not support generic board. Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file. Stop. We had to do "make clean" before building the microblaze board. This commit fixes this unconvenience. Move generic board sanity check to "prepare1" target, which is run after generation of include/autoconf.mk. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-25kbuild: get back DTB at the top directoryMasahiro Yamada
Commit 6ab6b2af deleted ./u-boot.dtb because it was a copy of dts/dt.dtb. But Simon suggested to keep u-boot.dtb at the top directory because it is a build output. After discussions, we agreed on revival of ./u-boot.dtb.

2014-02-25kbuild: move asm-offsets.h rules to ./KbuildMasahiro Yamada
Generate include/generated/generic-asm-offsets.h and include/generated/asm-offsets.h in ./Kbuild. This commit also changes the include guard. Before this commit, __ASM_OFFSETS_H__ was used for both of them. So we could not include generic-asm-offsets.h and asm-offsets.h at the same time. This commit renames the include guard of the former to __GENERIC_ASM_OFFSETS_H__. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-02-25kbuild: consolidate version and timestamp headers generationMasahiro Yamada
- Generate include/generated/{timestamp.h, version.h} more simply by using filechk rule. - Add $(UBOOTRELEASE) variable and re-write u-boot.imx rule more simply. - Rename U_BOOT_VERSION in Makefile to UBOOTVERSION Before this commit, the same variable name, "U_BOOT_VERSION" was used for two different strings. One of them was defined in Makefile. It takes the form like "2014.01-rc1" and used in makefiles and script files. The other is defined in include/generated/version.h It takes the form like "U-Boot 2014.01-rc1-00010-gbe6d426-dirty" and used in C and Aseembler. It is confusing when grepping the source tree. So, this commit renames the former to UBOOTVERSION. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-02-19kbuild: support simultaneous board configuration and "make all"Masahiro Yamada
This commit fixes two problems: [1] We could not do board configuration and "make all" in one command line. For example, the following did not work as we expect: $ make sandbox_config all Configuring for sandbox board... make: Nothing to be done for `all'. [2] mixed-target build did not work with -j option For example, the following did not work: $ make -j8 sandbox_config u-boot Makefile:481: *** "System not configured - see README". Stop. make: *** [u-boot] Error 2 make: *** Waiting for unfinished jobs.... Configuring for sandbox board... Going forward, we can do $ make -j8 sandbox_config all This is the same as $ make sandbox_config $ make -j8 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19kbuild: use scripts/Makefile.cleanMasahiro Yamada
This commit refactors cleaning targets such as clean, clobber, mrpropper, distclean with scripts/Makefile.clean. By using scripts/Makefile.clean, we can recursively descend into subdirectories and delete generated files there. We do not need add a big list of generated files to the "clean" target.

2014-02-19kbuild: change the top Makefile to more Kbuild-ish structureMasahiro Yamada
This commit changes the top Makefile to handle various targets nicely. Make targets are divided into four categories: - mixed-targets We can call a configuration target and build targets at one command line like follows: $ make <board_name>_config u-boot They are handled one by one. - config targets <board_name>_config - no-dot-config-targets Targets we can run without board configuration such as clean, mrproper, distclean, TAGS, %docs, etc. - build targets The other target which need board configuration.

2014-02-19Makefile: remove a cleaning target "tidy"Masahiro Yamada
Before this commit, "make tidy" did "make clean" + delete "*.depend*" files. But, we do not have "*.depend*" files any more, which means "make tidy" is the same as "make clean". This commit removes the redandant target "tidy". Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-02-19kbuild: generate {spl, tpl}-autoconf.mk only when it is necessaryMasahiro Yamada
Before this commit, {spl,tpl}-autoconf.mk was always generated at the top Makefile even if SPL(TPL) build was not selected.

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.

2014-02-19kbuild: change out-of-tree buildMasahiro Yamada
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>

2014-02-19Makefile: move more flags to the top MakefileMasahiro Yamada
Before this commit, most of compiler flags were defined in config.mk. But it is redundant because config.mk is included from all recursive make. This commit moves many complier flags to the top Makefile and export them. And we use new vaiarables to store them: KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS. This will allow us to switch more smoothly to Kbuild. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-02-19Makefile: move some variable definitions to the top MakefileMasahiro Yamada
This commit moves some variable definitions from config.mk to the top Makefile: - HOSTCC, HOSTCFLAGS, HOSTLDFLAGS - AS, LD, CC, CPP, etc. - SHELL (renamed to CONFIG_SHELL) I'd like to slim down config.mk file because it is included from all recursive make. It is redundant to re-define the variables every time descending into sub directories. We should rather define them at the top Makefile and export them. U-Boot makefiles has been used "SHELL" variable to store shell chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL". We should never use "SHELL" variable because it is a special variable for GNU Make. Changing SHELL may cause unpredictable side effects whose root cause is usually difficult to find. We should use a generic variable name "CONFIG_SHELL". We should not use the syntax as follows either: rm -f $(obj)tools/env/{fw_printenv,fw_setenv} This depends on "bash" although GNU Make generally invokes "sh" to run the each rule.
