| * | defaultenv-2: Make use of nonvolatile variablesSascha Hauer2014-11-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the variable assignments previously done in /env/config-board to non volatile variables in /env/nv/. This makes the settings adjustable by the user without editing a file. Most of the changes are simple conversions which for many boards makes /env/config-board unnecessary. Some boards had some logic to assign global.boot.default based on the current bootsource. This has been moved to /env/init/bootsource. An additional check is added to not overwrite a nv.boot.default should it exist. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | globalvar: Add support for printing all global variablesSascha Hauer2014-11-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This could previously only be done with 'devinfo global'. While this is still possible this adds a more direct access via the globalvar command. This variant also adds a '*' in front of the variable if the corresponding non volatile variable exists. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | Add support for non volatile variablesSascha Hauer2014-11-063-0/+176
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds (back) support for non volatile variables. Non volatile variables are variables which are stored in the environment over reboot. They are used in the same way as the global variables, but with a 'nv' command and device. The variables are stored under /env/nv/, one variable per file. Adding a nv variable automatically adds a global variable with the same name. Changing a nv variable also changes the same global variable, but not the other way round. This allows for example to configure the username as: nv user=sha; saveenv Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

I have seen the problem using usb sticks. Although partitioning and formatting them under linux. The file system type field in the mbr remains there which causes the wrong detections as FAT32 type and not as mbr.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This framework handles a list of registered Firmware programming handlers to unify a firmware programming interface by hiding the details how to program a specific Firmware in its handler. This is created with FPGAs in mind but should be usable for other devices aswell. A user has two possibilities to load a firmware. A device file is create under /dev/ which can be used to copy a firmware to. Additionally a firmwareload command is introduced which can list the registered firmware handlers and also to upload a firmware.

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>
