* bootm: fit: add option to add DT snipped that contains fit public keyMarc Kleine-Budde2018-02-201-0/+6
| | | | | | | | | | | | | | | | This makes it easier for build systems to include a configurable dts snippet which holds the public keys for FIT images. Usage: Add to your dts: #ifdef CONFIG_BOOTM_FITIMAGE_PUBKEY #include CONFIG_BOOTM_FITIMAGE_PUBKEY #endif Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* build: fix that the bbenv file is always rebuiltSam Ravnborg2018-01-051-1/+1
| | | | | | | | | | | | | | | From ac9ca6505d5b887c351117d9c033c8a76cc77125 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg <sam@ravnborg.org> Date: Tue, 26 Dec 2017 18:05:14 +0100 Subject: [PATCH 3/4] build: fix that the bbenv file is always rebuilt Use if_changed in rule for bbenv file. This avoids re-builds. The target is already assigned to extra-y - so the kbuild logic will work as expected.

* new make helper to decode binaries using base64Uwe Kleine-König2017-06-011-0/+6
| | | | | | | | | | | | | | | | | | This is helpful to provide mvebu binary.0 images with a patch. When added directly a binary patch is needed which isn't understood by patch(1). As it's (at least) unclear if these images are distributable in general I don't provide a patch making use of this, but the pattern is as follows: Add $(obj)/start_netgear_rn2120.pblx.kwbimg: $(board)/netgear-rn2120/binary.0 to images/Makefile.mvebu and then put a binary.0.base64 into the board folder.

* Add comp_copy function for use with CONFIG_IMAGE_COMPRESSION_NONESascha Hauer2016-09-151-0/+8
| | | | | | | | | | The Makefile compression commands all append the size of the uncompressed image. With CONFIG_IMAGE_COMPRESSION_NONE simply 'shipped' is used which does not append the size. Add and use a special comp_copy function which adds the size. This helps us to get the uncompressed image size in the startup code later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* kbuild: handle multi-objs dependency appropriatelyMasahiro Yamada2014-11-271-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The comment in scripts/Makefile.build says as follows: We would rather have a list of rules like foo.o: $(foo-objs) but that's not so easy, so we rather make all composite objects depend on the set of all their parts This commit makes it possible! For example, assume a Makefile like this obj-m = foo.o bar.o foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this patch, foo.o depends on all of foo1.o foo2.o bar1.o bar2.o. It looks funny that foo.o is regenerated when bar1.c is updated. Now we can handle the dependency of foo.o and bar.o separately.

* Add support for metadata in barebox imagesSascha Hauer2014-08-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's often useful to get some information about a barebox image before starting or flashing it. This patch introduces barebox Image MetaData (IMD). When enabled a barebox image will contain a list of tags containing the desired information. We have tags for: - the barebox release (2014.07.0-00160-g035de50-dirty) - the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014) - the board model the image is intended for - the device tree toplevel compatible property Also there is an additional generic key-value store which stores parameters for which no dedicated tag exists. In this patch it is used for the memory size an image supports. Since there is no fixed offset in a barebox image which can be used for storing the information, the metadata is stored somewhere in the image and found by iterating over the image. This works for most image types, but obviously not for SoC images which are encoded or encrypted in some way. There is a 'imd' tool compiled from the same sources for barebox, for the compile host and for the target, so the metadata information is available whereever needed. For device tree boards the model and of_compatible tags are automatically generated. Example output of the imd tool for a Phytec phyFLEX image: build: #889 Wed Jul 30 16:08:54 CEST 2014 release: 2014.07.0-00167-g6b2070d-dirty parameter: memsize=1024 of_compatible: phytec,imx6x-pbab01 phytec,imx6dl-pfla02 fsl,imx6dl model: Phytec phyFLEX-i.MX6 Duallite Carrier-Board Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | To build an object file from a device tree currently we currently have to add them to the Makefile twice, once to dtb-y and once to obj-y. This patch introduces obj-dtb-y and pbl-dtb-y to directly compile a device tree object file for inclusion in the barebox binary or the pbl respectively. The now unneeded dtb-y targets are removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the same Linux commit from Stephen Warren: commit b40b25fff8205dd18124d8fc87b2c9c57f269b5f Author: Stephen Warren <swarren@nvidia.com> Date: Wed Mar 6 10:58:37 2013 -0700 kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp Replace cmd_dtc with cmd_dtc_cpp, and delete the latter. Previously, a special file extension (.dtsp) was required to trigger the C pre-processor to run on device tree files. This was ugly. Now that previous changes have enhanced cmd_dtc_cpp to collect dependency information from both gcc -E and dtc, we can transparently run the pre- processor on all device tree files, irrespective of whether they use /include/ or #include syntax to include *.dtsi.
