* ARM iMX53: avoid magic number addressing for internal RAMAlexander Kurz2016-06-271-2/+3
| | | | | | | | | The imx53 SOC features 128kB of internal SRAM which is commonly used in early stages of barebox to store the stack. Avoid magic numbers while addressing this RAM. Signed-off-by: Alexander Kurz <akurz@blala.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add support for metadata in barebox imagesSascha Hauer2014-08-071-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * Set model and hostname at boardlevelSascha Hauer2013-08-162-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | Use MMC_CAP_ names instead of MMC_MODE_. This makes it more clear that these are capabilities of host/card and do not refer to the current mode. These are in line with the Linux Kernel except for MMC_CAP_MMC_HIGHSPEED_52MHZ which could be fixed later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: tqma53: call SoC lowlevel function earlySascha Hauer2013-04-052-1/+2
| | | | | | | | | | | With CONFIG_MMU_EARLY enabled the board does not survive the call to imx53_init_lowlevel(). This should not happen, but the reasons are currently unknown. This works on other boards like the i.MX53 QSB. This patch moves the call to imx53_init_lowlevel to barebox_arm_reset_vector() which is executed with MMU disabled.

* | defenv-2: bring back /env/configSascha Hauer2012-11-013-16/+7
|/ | | | | | | | | | | | | | The idea of having /env/init/* scripts was to make the configuration more flexible and customizable for boards. It turned out though that people (including myself) do not find the place where they should change these settings. So this patch brings back /env/config for defenv-2. The individual env/init/* scripts are removed and their content is added to /env/init/config-board. This makes the values from /env/init/config-board the board specific defaults which can be overwritten in /env/config. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
