| * | Add a Firmware programming frameworkJuergen Beisert2014-09-093-0/+215
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Introduce message logging supportSascha Hauer2014-09-302-3/+129
| | | | | | | | | | | | | | | | | | | | This adds a buffer for log messages and a 'dmesg' command to print the messages. The log buffer is implemented as log objects rather than a string buffer. This makes it easy to implement limiting the messages, cleaning the buffer and timestamping the messages. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This now issues a warning each time the board is started. Revert the commit for now. A better solution might be to check if the same SDRAM region already exists before trying to register it again.

This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.

| * | | | Add support for metadata in barebox imagesSascha Hauer2014-08-074-1/+357
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * common: resource: print conflicts as warningAlexander Aring2014-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Crazy things happen if there are resource conflicts and a device probe runs dev_request_mem_region. The dev_request_mem_region returns a start pointer which is zero. The probe function doesn't check on this and probing the device on zero base address. To debug this in debug log level there are many other outputs. This patch replace the debug print to a warning printout. A conflict should normally never happen. If there is a conflict it's much easier to see it with this patch. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
