* scripts: imx-image: make read_file behaviour consistentSascha Hauer2019-02-111-13/+11
| | | | | | | | | | When read_file fails then it exits the program in most cases. Let's exit the program when stat() fails aswell, so that we *always* exit the program on failure. Drop all error handling for read_file since that's no longer necessary and rename the function to xread_file to make clear it won't fail. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* scripts: imx-image: Add support for max_load_size optionSascha Hauer2018-11-302-1/+22
| | | | | | | | | | | | | When an image is loaded to SRAM we can normally only load a part of the full image, limited by the available space in SRAM. We currently load the pblb image which is the executable part of the PBL without the compressed barebox payload. We are going to link the compressed barebox image into the pbl image though, so we can't see the desired load size from outside the image anymore. This adds a max_load_size option to set this size explicitly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* scripts: imx-image: fix first instruction in i.MX8MQ headerLucas Stach2018-11-092-1/+7
| | | | | | | | | | | | | | | The instruction being patched in was a branch to 0x24000, instead of the intended 0x9000. This doesn't matter when starting the image from a regular boot source, but breaks starting the image via bootm, as we rely on the jump in the first header instruction taking us to the actual code. As the code offset changes depending on the presence of the signed HDMI firmware, compute the offet dynamically while building the image.

| * scripts: imx: Support encrypted boot with HABv4Marcin Niestroj2018-09-042-11/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .imxcfg configuration files support few more commands, all starting with "hab_encrypt" string. That way it is possible to easily ignore these commands, when image encryption was not requested. Hence, we can use single .imxcfg file to generate signed and encrypted images in the same build. Images are encrypted in place by Freescale Code Signing Tool (cst), using Data Encryption Key (DEK). This key needs to be encapsulated by processor's hardware encryption engine to produce DEK blob, which is unique for each device. DEK blob needs to be part of CSF area, so we make enough space on the end of image to simply append it later, e.g. during device flash procedure. Introduced code was developed and tested on NXP i.MX6UL platform. Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * scripts: imx: add optional argument to hab_blocks commandMarcin Niestroj2018-09-041-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hab_blocks command is used to specify image authentication blocks for HAB. Currently it was configured to authenticate full barebox image. However in case of booting from SD card and adding MBR partition table, HAB authentication fails, as final boot image is modified. Add an optional argument to hab_blocks command, to select between 3 types of authentication areas: - full: whole barebox image will be authenticated (this is default to keep compatibility), - from-dcdofs: image area up to dcdofs is not authenticated, so any changes up to dcdofs are possible, - skip-mbr: image area from 440 to 512 bytes is excluded from beeing authenticated, which allows to add / modify MBR partition table after building barebox image.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some vendors fuse their devices so that the IMX USB ROM loader identifies itself with a different Vendor and Product ID on USB enumeration. Currently, imx-usb-loader will refuse to detect and work with such devices, so let's teach it. Because we cannot easily detect the device type from the USB ID in this case, introduce the new command line parameter -d <type> to specify the device type to use on the device path specified with -p <path>, even if the VID/PID pair of that device is unknown. The device name is sourced from the "name" field of the imx_ids array of known devices at the top of the file. Using "-d list" will print a list of known device types. Using -d without -p will not do anything useful, except generate a warning. Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | scripts: imx-usb-loader: fail early if the USB device path does not matchRoland Hieber2018-09-071-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | find_imx_dev() loops through all USB devices, tries to open them, and then compares the chosen device path (given with -p on the command line) to the path of the currently opened device. The device path can be checked earlier, opening the device is not neccessary. We fail early here because in the next commit we want to enable the user to force using a device by specifying its path. Opening every single device available on the system then leads to unnecessary error messages for all devices that do not match the provided path.

|/ | | | | | | | | | | | | | Boot header on i.MX8MQ SoC allows embedding signed HDMI firmware images that are used by mask ROM code during the very early stages of boot. Since providing that firmware appear to be necessary to enable SoC's HDMI/DP functionality extend imx-image tool to support this feature. To do that add code implementing "signed_hdmi_firmware" keyword, which allows users to specify a path to a binary blob containing all of the necessary headers and footers as well firmware data and code sections (this is how such images are provieded by NXP) Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the following: 1. Assembly code, namely "b 0x1000" instruction, in bb_header[] assumes that i.MX image header occupies first HEADER_LEN bytes and bootloader executable is located right after. 2. Code in imx_image_size() assumes that i.MX image header is HEADER_LEN bytes 3. Original code handling v2 header allocated more than HEADER_LEN buffer to store IVT + boot data + DCD. However, the code writing that buffer to disk is only set up to use first HEADER_LEN bytes and to silently discard the rest as a side effect. Let's be conservative and limit total size of v2 header to not exceed Inital Load Region (4K or HEADER_LEN) to match what's being done for v1.
