* Makefile: fix ctags/etags clean targetsIgor Grinberg2014-07-22-1/+1
| | | | | | | | | | | | | | Commit efcf861 (kbuild: use scripts/Makefile.clean) refactored the cleaning targets and accidentially replaced the actually generated "ctags" and "etags" files in the file list by "tags" and "TAGS". "tags" and "TAGS" are not part of the Makefile build targets and therefore should not be a part of the list for clean targets. Substitute the actually generated files instead, to fix the clean targets behavior. Cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>

| | | | | | | | | | | | | | | | Commit 9e41403 (kbuild: change out-of-tree build) changed the U-Boot build working directory to the output tree for the out-of-tree builds. This broke the {c,e}tags/cscope build targets as TAG_SUBDIRS variable collected directories based on assumption that the build working directory is the U-Boot source tree directory. Fix the {c,e}tags/cscope build targets by adding the $(srctree) prefix. Also, remove the $(obj) prefix from the etags build target to finish the $(obj) prefix removal started by the same commit.

* fdt: Add DEV_TREE_BIN option to specify a device tree binary fileSimon Glass2014-06-11-1/+1
| | | | | | | | | | | | | | In some cases, an externally-built device tree binary is required to be attached to U-Boot. An example is when using image signing, since in that case the .dtb file must include the public keys. Add a DEV_TREE_BIN option to the Makefile, and update the documentation. Usage is something like: make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb Signed-off-by: Simon Glass <sjg@chromium.org>
* Check that u-boot.bin size looks correctSimon Glass2014-06-11-1/+13
| | | | | | | | | | | | Check that the image size matches the size we get from u-boot.bin. If it doesn't, that generally means that some extra sections are being added to u-boot.bin, meaning that it is not possible to access data appended to the U-Boot binary. This is used for device tree, so needs to work. This problem was introduced by commit b02bfc4. By adding a test we can prevent a reccurence. Signed-off-by: Simon Glass <sjg@chromium.org>
* Makefile: fix clang warnings due to clang supportJeroen Hofstee2014-06-11-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building u-boot tools with clang as a host compiler e.g. on FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools` leads to many warnings [1] for every compiler invocation since commit 598e2d33. Part of mentioned commit imports linux patches: - kbuild: LLVMLinux: Adapt warnings for compilation with clang - kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang No version of clang supports the gcc fno-delete-null-pointer-checks though, but it is only passed to clang. Gcc does not have the clang specific Qunused-arguments for the target. Furthermore several warnings are disabled which aren't encountered in u-boot. Since such a build has worked for quite some time and works after removing these changes, just remove the clang specific handling to restore normal building with clang as hostcc. [1] Actual warnings ------------------- GEN include/autoconf.mk.dep arm-freebsd-gcc: unrecognized option '-Qunused-arguments' HOSTCC scripts/basic/fixdep clang: warning: argument unused during compilation: '-fno-delete-null-pointer-checks' cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, the top-level linker script u-boot.lds used a simple $(call if_changed) check when generated.

* | 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).

| | | | | | | | | | | | | | | | | | | | | | | | The tools "buildman" and "patman" are written in Python. When we run them, "*.pyc" files are created under tools/buildman, tools/patman directories. They should be cleaned up by "make distclean". Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Tom Rini <trini@ti.com> Acked-by: Simon Glass <sjg@chromium.org>
