* common: add generic CONFIG_UBSAN plumbingAhmad Fatoum2019-09-091-0/+8
| | | | | | | | | | | | | | -fsanitize=undefined allows compile-time instrumentation of code to detect some classes of runtime undefined behavior. In preparation for allowing arches to provide infrastructure in support of this feature, add some generic UBSAN options and associated plumbing. These are only shown in the debug menu when the arch selects the appropriate symbol. The option is named equally to their Linux counterparts.

* images/mvebu: Convert Armada machines to mvebuimgUwe Kleine-König2019-06-131-0/+3
| | | | | | | | | | | | The results are bytewise identical apart from armada-xp-db where the (AFAIK unused) parameters for the binary header are different (i.e. 0000005b 00000000 instead of 0000005b 00000068 for all other boards). The advantage is that the build system now knows about the binary headers and changes to them result in a rebuild of the images.

* kbuild: Use ls(1) instead of stat(1) to obtain file sizeMichael Forney2019-05-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stat(1) is not standardized and different implementations have their own (conflicting) flags for querying the size of a file. ls(1) provides the same information (value of st.st_size) in the 5th column, except when the file is a character or block device. This output is standardized[0]. The -n option turns on -l, which writes lines formatted like "%s %u %s %s %u %s %s\n", <file mode>, <number of links>, <owner name>, <group name>, <size>, <date and time>, <pathname> but instead of writing the <owner name> and <group name>, it writes the numeric owner and group IDs (this avoids /etc/passwd and /etc/group lookups as well as potential field splitting issues). The <size> field is specified as "the value that would be returned for the file in the st_size field of struct stat". To avoid duplicating logic in several locations in the tree, create scripts/file-size.sh and update callers to use that instead of stat(1).

| * pbl multiimage: Allow to check image sizesSascha Hauer2019-03-131-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PBL images are often constrained in size by limitations exposed by the SoCs SRAM size or partition sizes on the boot device. So far we tried to configure these limits in Kconfig, but with PBL multi images and thus different limitations for the different supported images this no longer works. This patch has another approach for it: During build time make variables containing the relevant sizes for each image are created. These are: PBL_CODE_SIZE_$(symbol) PBL_MEMORY_SIZE_$(symbol) PBL_IMAGE_SIZE_$(symbol) PBL_CODE_SIZE_$(symbol) contains the pure code size of the PBL, it should be smaller than the available SRAM during boot. Normally the PBL's bss segment also needs to be in the initial SRAM, for this case PBL_MEMORY_SIZE_$(symbol) is the relevant variable. PBL_IMAGE_SIZE_$(symbol) contains the full size of the PBL image including the compressed payload (but without any image headers created later by SoC specific image tools). $(symbol) is a placeholder for the start symbol used for this PBL image, thus for the i.MX53 QSB with entry start_imx53_loco PBL_CODE_SIZE_start_imx53_loco will be created. The images/Makefile.* can use these variables directly to check sizes or specify the same variables with a "MAX_" prefix. So when images/Makefile.imx specifies MAX_PBL_CODE_SIZE_start_imx53_loco = 0x10000 then the build system will make sure that the PBL code for the QSB will not get bigger than 64KiB. Also included in this patch are the size restrictions for the i.MX8MQ images as an example how to use this. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* defaultenv: Fix dependenciesSascha Hauer2019-02-271-1/+3
| | | | | | | | | | | | | The defaultenv should be rebuilt once a file in it has changed. the genenv script always generates the environment file to a temporary file. Only if it has changed to the last target file the temporary file is moved over the target file. This means we always have to call genenv, thus replace "if_changed" with "cmd". With this dependencies are correctly tracked. New or changed files result in new image builds whereas unchanged environments do not unnecessarily result in new images.

| | | | | | | | | | | | | | | | | | | | | | | | Recent kernel versions run flex and bison to generate lexers and parsers from real source files such as *.l and *.y .

* ARM: i.MX: make HAB certificate pathes explicitly overwritableSascha Hauer2018-09-071-6/+11
| | | | | | | | | | | | | | | | | When building HAB images for i.MX we have to specify some pathes to the certificates. This can be done with Kconfig variables. For better build system integration we also want to be able to specify the pathes in environment variables. This currently doesn't work as we specify the variables from the environment with the -D option to cpp, but also include generated/autoconf.h which overwrites the variables with the values from Kconfig. To overcome this introduce a Kconfig switch that explcitly selects whether we want to have the variables from Kconfig or the environment. Also, only pass the variables from the environment when explicitly wanted. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

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.

* 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>

* / ARM: generate imx dcd.S files as *.dcd.SSascha Hauer2013-07-101-1/+1
|/ | | | | | | | The compiled in dcd images generate an intermediate assembly file. Instead of generating them as *.S generate them as *.dcd.S to better identify them as generated files. These are then added to .gitignore. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
