* scripts: imx-image: rename dcdofs to ivtofsSascha Hauer2020-07-141-1/+1
| | | | | | | | | This renames the dcdofs config option in the imx-image tool to ivtofs. dcdofs is a misnomer. The DCD (Device Configuration Data) is only one part of the data linked into the IVT (Image Vector Table), but the meaning of the option is really the latter, not the former.

* arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-05-251-15/+3
| | | | | | | | | | | | | | | | This adapts all files that were identifed by licensecheck (https://salsa.debian.org/build-common-team/licensecheck.git) as licensed under the GPL. The advantage is that these specifiers are machine-parseable which helps license conformance, e.g. for packaging barebox in Debian. While touching these files also do some minor comment reformatting to get some uniform layout.

* ARM: Cleanup stack offset cargo cultSascha Hauer2019-09-091-1/+1
| | | | | | | | | Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16 bytes from the stack top. This is unnecessary as on ARM we have a stack that decrements before storing values. Substracting this offset probably goes back to the U-Boot version we forked from. Stop this now.

* ARM: boards: Harmonize barebox_arm_reset_vector() prototypeSascha Hauer2019-03-181-1/+1
| | | | | | | | | | | | barebox_arm_reset_vector() is a global function but we never provided a prototype anywhere. The prototypes differ for the different boards, so to provide a common prototype we must harmonize them. void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2) Should be suitable for all boards.

* defaultenv: add defaultenv-1 in boards via defaultenv_append_directory()Sascha Hauer2016-10-103-0/+5
| | | | | | | | | | | | | | | | | | | | Currently it's hardcoded for each board which defaultenv version is used. This is unfortunate since some people like the other defaultenv version better and may want to select it. This patch removes the board specific environment path CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via: if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC)) defaultenv_append_directory(defaultenv_<board>); This way we can make sure that the defaultenv-1 board specific bits are only compiled in when defaultenv-1 is actually in use. The next step is to make the defaultenv version selection a user visible choice. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Set model and hostname at boardlevelSascha Hauer2013-08-162-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: move exception vectors away from start of binarySascha Hauer2012-02-281-1/+2
| | | | | | | | | | | | | | | | Traditionally U-Boot and barebox have the exception vectors at the start of the binary. There is no real reason in doing so, because in the majority of cases this data will not be at 0x0 where it could be used as vectors directly anyway. This patch puts the vectors into a separate linker section and defines an head function which is placed at the start of the image instead. Putting this in a separate function also has the advantage that it can be placed at the start of images which require an additional header like several Freescale i.MX images. As the head function contains the barebox arm magic those images can now also be detected as barebox images. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
