* scripts: imx-usb-loader: implement DCD v2 check commandAlexander Kurz2017-02-222-2/+109
| | | | | | | | | | | | The DCD v2 check command supported by i.MX53 and later SoC polls a given memory location as long as a given condition is true. Enable imx-usb-loader to perform this check. When the timeout is hit, imx-usb-loader returns an error. For practical reasons the timeout computation will differ from the native implementation, since performing check commands via USB will be much slower compared to native processing.

* scripts: imx-image: Allow to create HAB signed images suitable for USB uploadSascha Hauer2016-02-041-6/+54
| | | | | | | | | | | | | | | | | | | | | For USB upload we must execute the DCD table manually and invalidate the DCD table in the uploaded image afterwards to prevent the ROM from executing the DCD data again. Doing this changes the image and thus also invalidates the signature. To make HAB signed images suitable for USB upload possible we add an option to create HAB signed images suitable for USB upload. With this option the image is created like this: - The image is created like usual, but with already invalidated DCD data (DCD length is set to zero) - This image is then signed using the CST - After this the DCD data is made valid (Set DCD length to the real length) imx-usb-loader now finds valid DCD data, executes it and by invalidating the DCD data it restores the state the image had during signing.

| | | | | | | | | We invalidate the dcd data in the uploaded image since we already processed it manually. To do so we have set the dcd pointer to 0. Doing it this way prevents the ROM from executing the HAB code in debug mode. Use the dcd length instead to invalidate the dcd data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* scripts: imx: Allow to create signed imagesSascha Hauer2016-02-043-21/+167
| | | | | | | | | | | | | | | | This patch allows to call CST directly from imx-image to create signed images. CST is called whenever the config file contains the hab <str> commands which means a CSF is generated. Calling CST requires some quirks. First of all CST returns successfully whenever a CSF exists, no matter is the CSF actually contains something sensible or not. So to detect if CST has been called successfully we have to check if it generated output, not if it returned successfully. Then CST uses csfsig.bin as a temporary file which breaks when the tool is called multiple times at once, something which often happens in parallel builds. We therefore have to lock accesses to this file using flock(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* scripts: imx: Create CSF files from imx config fileSascha Hauer2016-02-042-1/+109
| | | | | | | | | | | | | | | | | | | | | | | This is the first step to support creating signed images directly with the imx-image tool. i.MX images must be signed using the Freescale CST tool. CST needs informations already present in the imx-image tool, so it's convenient to call CST directly from imx-image. CST takes CSF files (Command Sequence Files) as input. This patch supports generating CSF files from the imx-image configuration file. This adds three new commands to the config file: hab <str>: All options to the hab command are directly passed through to the CSF. hab_blocks: This generates the "Blocks =" line in the CSF. This is the place where the CSF needs information which is contained in the imx-image tool: The image size, the image filename and the load address. super_root_key <file>: For HABv3 the super root key hash is needed in the i.MX flash header. This command is used to specify the path to the super root key. Needed for HABv3 only. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* scripts: imx-usb-loader: Add -s and -i optionsSascha Hauer2016-02-021-1/+36
| | | | | | | | | | | | | | | | | | | Normally imx-usb-loader interprets and executes the DCD table from an uploaded image and invalidates the DCD before uploading the image itself to prevent the i.MX ROM code from executing it again. With HAB signed images this is not possible since invalidating the DCD table modifies the image which also makes the signature invalid. To support this usecase add two new options to imx-usb-loader: The -i option allows to pass in an external config file which can be used to setup SDRAM. The DCD table in the image can then be made empty so that the ROM does not see a second SDRAM setup. The -s option allows to skip interpreting the DCD table in the image. This may when some setup stuff is still in the images DCD table but shall be executed by the ROM and not by imx-usb-loader. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
