Here, u-boot.img = uImage header + u-boot.bin To use OF control with a separate devicetree, u-boot.dtb must be placed right after u-boot.bin. In this case, u-boot-dtb.bin is generally used. Here, u-boot-dtb.bin = u-boot.bin + u-boot.dtb We need u-boot-dtb.img to use both SPL framework and separate OF control at the same time. u-boot-dtb.img = uImage header + u-boot-dtb.bin For example, Zynq boards already define all of - CONFIG_SPL - CONFIG_OF_CONTROL - CONFIG_OF_SEPARATE So, the support of u-boot-dtb.img is urgent.

Now that the kernel does not use any of those macros, turn on -Werror=date-time if available, to keep it that way. The kernel already (optionally) records this information at build time in a single place; other kernel code should not duplicate that.

However, CONFIG_SPL_MAX_SIZE is used in the Makefile for padding the SPL when preparing an u-boot.ais image. By removing CONFIG_SPL_MAX_SIZE said commits broke the ais image of the da850evm and cam_enc_4xx configurations. This patch converts the u-boot.ais target to use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for padding the SPL and adds a #define CONFIG_SPL_PAD_TO where it is required.

Commit a8b993eb claims it fixes u-boot.lds rule by replacing $(call if_changed) with $(call filechk). But the problem had already been fixed by commit 395e60cd a few days before commit a8b993eb was posted. There is no reason to apply commit a8b993eb. What is worse is $(call filechk) is too strong to fix the problem and looks weird.

| | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, the top-level linker script u-boot.lds used a simple $(call if_changed) check when generated. That mechanism misses cases where a possible include file change induces a change in the u-boot.lds too. This patch converts it to a stronger check using ($call filechk) that will also notice differences in file contents and will catch changes due to pre-processing as well.

* | arm: mxs: Add support for generating signed BootStreamMarek Vasut2014-04-04-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

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 Yamada2014-03-07-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * kbuild: allow empty board directoriesMasahiro Yamada2014-03-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has compelled all boards to have board/${BOARD}/ or board/${VENDOR}/${BOARD}/ directory. Sometimes it does not seem suitable for some boards, for example Sandbox. (Is it a board?) And arcangel4 board has nothing to compile under the board directory. This commit makes the build system more flexible: If '<none>' is given to the 6th column (=Board name) of boards.cfg, Kbuild will not descend into the board directory.
