* lds: align RO_DATA_SECTION membersLucas Stach2019-12-201-0/+11
| | | | | | | | | | | | When using the RO_DATA_SECTION macro, all the individual components are put into the rodata section. As they now end up in the same section there is no alignment enforced between them anymore. This leads to unaligned start pointers when any of the components have a unaligned size. Enforce some alignment between them. Fixes: c5d38e920101 (lds: Add and use RO_DATA_SECTION macro) Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: zynq: move header generation to zynq_mkimageLucas Stach2019-11-111-2/+1
| | | | | | | | | | Instead of generating a suitable image header with linker magic, move all of this into zynq_mkimage. The configuration file format and parsing is based on imx-image. This gets us one step further on the road to proper multi-image support. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* rsa: Allow to directly compile in rsa public keysSascha Hauer2019-10-151-0/+6
| | | | | | | | | | | | | So far we relied on the U-Boot mkimage tool to generate us device tree snippets containing rsa public keys which we then compiled into barebox. Make this easier and allow to directly specify a filename or PKCS#11 URI in Kconfig. With this we no longer need the U-Boot mkimage tool here and no more external steps to prepare device tree snippets. With this rsa public keys can be directly compiled as C structs into barebox which is much more direct than putting it into the device tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* lds: Add and use RO_DATA_SECTION macroSascha Hauer2019-10-141-0/+11
| | | | | | | | | We have many different pointer arrays which we put into linker sections and each time there's one added we have to adjust all linker scripts. This adds a common RO_DATA_SECTION define and uses it for all architectures. This makes it easier to add a new linker array. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Make the start/end addresses part of the define to simplify things. While at it, add a BAREBOX_ prefix to the INITCALLS and EXITCALLS macros for consistency to the other defines.

* ARM: Initial OP-TEE supportSascha Hauer2019-06-071-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for OP-TEE, see https://www.op-tee.org/ barebox starts in secure mode as usual. When booting a kernel the bootm code also loads the optee_os binary. Instead of jumping into the kernel barebox jumps into the optee_os binary and puts the kernel execution address into the lr register. OP-TEE then jumps into the kernel in nonsecure mode. The optee_os binary is passed with the -t option to bootm or with global.bootm.tee. Optionally OP-TEE can be compiled into barebox using the builtin firmware feature. Enable the Kconfig option and place or link your tee binary as optee.bin into the firmware directory. The amount of SDRAM which is kept free for OP-TEE is configurable. This patch was tested on a i.MX6 Nitrogen6x board.

* ratp: implement generic command supportAleksander Morgado2018-03-011-0/+2
| | | | | | | | | | | | | | | | | | | The RATP implementation now allows executing generic commands with a binary interface: binary requests are received and binary responses are returned. Each command can define its own RATP request contents (e.g. to specify command-specific options) as well as its own RATP response contents (if any data is to be returned). Each command is associated with a pair of numeric unique request and response IDs, and for easy reference these IDs are maintained in the common ratp_bb header. Modules may override generic implemented commands or include their own new ones (as long as the numeric IDs introduced are unique).

| | | | | | | | | | In barebox_non_pbl_start() we do not run at the address we are linked at, so we must read linker variables using ld_var(). Since ld_var() current is not available on arm64 we create two zero sized arrays, one at the begin of the image and one at the end. The difference between both is the image size we are looking for.

* | 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.

| | | | | | | | | | | 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.
