* | Add support for metadata in barebox imagesSascha Hauer2014-08-071-0/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Load PBL into SRAMDavid Vincent2014-02-091-0/+13
| | | | | | | | | | This allows to load all the lowlevel init code, including the uncompressor, inside SRAM and not just the bare init part.

* mtd: nand: update to v3.11-rc1Sascha Hauer2013-07-231-1/+3
| | | | | | | | | | | | | | | | | | This updates the NAND stuff to Linux-3.11-rc1. It is synchronized as best as we can get: - locks removed - The splitting in different files we had to better support different features has been dropped. Instead this is now done mostly with the use of __maybe_unused Some barebox adjustments are forward ported, like: - Allow partial page writes - Optionally allow to erase bad blocks - check for all_ff before writing a page Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: Add image end sectionSascha Hauer2013-06-261-0/+1
| | | | | | | | | | | In the upcoming multi image build process we will cat images together. To find the concatenated image we need to reliably find the end of the current binary. This adds a dummy section at the end of a pbl binary. Its only purpose is to mark the end of the image. The multi image patches will add something to this section so that it doesn't get discarded by the linker. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option In some case we need to copy the PIGGYDATA as the link address as example we run from SRAM and shutdown the SDRAM/DDR for reconfiguration but most of the time we just need to copy the executable code. based on Sascha Hauer Add compressed image support Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

The barebox will skip it. Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and implement a dummy panic.
