Actually imx-image puts the image at 4k but it seems that the i.MX35 bootrom copies only from 8k as it expects that there is a copy of the first 0-4k in 4k-8k (and is supposed to use this copy if there is an ECC error in the first 4k) as we can see in the following lines : barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x0 00000000: ea0003fe eafffffe eafffffe eafffffe ................ 00000010: eafffffe eafffffe eafffffe eafffffe ................ 00000020: 65726162 00786f62 00000000 00000000 barebox......... =-> header is @ 0 in flash barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x1000 00001000: 56341200 00000000 0001eda1 00000000 ..4V............ 00001010: 00000000 00000000 00000000 00000000 ................ =-> so we have data @ 0x1000 in flash barebox@Eukrea CPUIMX35:/ md 0x87f00000 87f00000: 00000000 00000000 00000000 00000000 ................ 87f00010: 00000000 00000000 00000000 00000000 ................ =-> but we don't find this data in RAM barebox@Eukrea CPUIMX35:/ md -s /dev/nand0 0x2000 00002000: ea000012 eafffffe eafffffe eafffffe ................ 00002010: eafffffe eafffffe eafffffe eafffffe ................ 00002020: 65726162 00786f62 00000000 00034272 barebox.....rB.. =-> so we have the image @ 0x2000 in flash barebox@Eukrea CPUIMX35:/ md 0x87f01000 87f01000: ea000871 eafffffe eafffffe eafffffe q............... 87f01010: eafffffe eafffffe eafffffe eafffffe ................ 87f01020: 65726162 00786f62 87f02000 0003b520 barebox.. .. ... =-> and we find it in RAM Signed-off-by: Eric Bénard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | The length of two subsequent check commands was incorrectly calculated.

| |/ | | | | | | | | | | | | | | | | | | Instead of bailing out skip unknown tags. These tags are usually doing operations to poll for a certain register state. The correct solution is to implement this register polling, but for now delay execution for a while and assume the register has the correct state afterwards.

* / scripts: mk-am3xxx-spi-image: fix wrong assumptions about SPI imagesSascha Hauer2014-09-263-42/+38
|/ | | | | | | | | | | | | | | | | | | | | | | | We assumed that there is a special image format for SPI. This is not the case. The AM33xx can boot either images generated with omap_signGP or raw images which only have the image size and load address in front of the image. Whether these images are booted from SPI or another boot medium doesn't matter. The only special thing about SPI is that the image is in big endian format. - renames mk-am3xxx-spi-image.c to mk-omap-image.c as the image format is not only supported by AM3xxx but also by the OMAP SoCs - removes the option to specify the SoC - introduces -s to build a big endian image - detects if an image already is an image generated with omap_signGP So the behaviour is like this: raw image -> mk-omap-image -> prepend size/address -> image for SD/MMC raw image -> mk-omap-image -s -> prepend size/address, big endian swap -> image for SPI CH image -> mk-omap-image -> nothing, input == output CH image -> mk-omap-image -s -> big endian swap -> image for SPI Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Add support for metadata in barebox imagesSascha Hauer2014-08-074-1/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * dtc: compile fdtgetSascha Hauer2014-08-0713-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | We need fdtget in subsequent patches, so compile it. Unfortunately this is not straight forward. fdtget needs libfdt, but the Kernel Build System is not prepared for compiling libraries for the host or binaries from files in multiple directories. This patch moves the libfdt files to the dtc toplevel directory and compiles fdtget as a binary from multiple source files but from the same directory.

| * make: build device trees with obj-dtb-y and pbl-dtb-ySascha Hauer2014-08-071-0/+7
| | | | | | | | | | | | | | | | | | | | | | To build an object file from a device tree currently we currently have to add them to the Makefile twice, once to dtb-y and once to obj-y. This patch introduces obj-dtb-y and pbl-dtb-y to directly compile a device tree object file for inclusion in the barebox binary or the pbl respectively. The now unneeded dtb-y targets are removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an external environment storage should be used in very rare and special cases, the intentional behaviour should be to ignore the external environment and always fall back to the built-in environment. By storing an empty "to be ignored" environment into the external environment a confusing error message about invalid CRC sums will go away and still the built-in environment is used. With this new option we can force the intentional behaviour. Signed-off-by: Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
