2020-01-07spl: fit: Allow the board to tell if more images must be loaded from FITJean-Jacques Hiblot
spl_fit_get_image_name() is used to get the names of the images that the SPL must load from the FIT. It relies on the content of a property present in the FIT. The list of images is thus statically defined in the FIT. With this scheme, it quickly becomes hard to manage combinations of more than a handful of images. To address this problem, give the board driver code the opportunity to add to the list of images. The images from the FIT property are loaded first, and then the board_get_fit_loadable() is called to get more image names.

2019-08-26spl: fit: use U-Boot device tree when FIT image has no device treeLukas Auer
As part of the SPL FIT boot flow, the device tree is appended to U-Boot proper. The device tree is used to record information on the loadables to make them available to the SPL framework and U-Boot proper. Depending on the U-Boot device tree provider, the FIT image might not include a device tree. Information on the loadables is missing in this case. When booting via firmware bundled with the FIT image, U-Boot SPL loads the firmware binary and U-Boot proper before starting the firmware. The firmware, in turn, is responsible for starting U-Boot proper. Information on the memory location of the U-Boot proper loadable must be available to the SPL framework so that it can be passed to the firmware binary. To support this use case when no device tree is found in the FIT image, fall back to the U-Boot device tree in this situation. At the same time, update the comment to remove the note that the destination address must be aligned to ARCH_DMA_MINALIGN. Alignment is only required as an intermediate step when reading external data. This is automatically handled by spl_fit_append_fdt(). After reading the external data, it is copied to the specified address, which does not have to be aligned to ARCH_DMA_MINALIGN.

2019-07-17spl: Make image loader infrastructure more universalAndreas Dannenberg
The current U-Boot SPL image loader infrastructure is very powerful, able to initialize and load from a variety of boot media however it is strongly geared towards loading specific types of images in a very specific way. To address the need being able to use this infrastructure to load arbitrary image files go ahead and refactor it as follows: - Refactor existing spl_mmc_load_image function into superset function, accepting additional arguments such as filenames and media load offset (same concept can also be applied toother spl_XXX_load_image functions) - Extend the loader function to "remember" their peripheral initialization status so that the init is only done once during the boot process, - Extend the FIT image loading function to allow skipping the parsing/ processing of the FIT contents (so that this can be done separately in a more customized fashion) - Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function, invoking the newly refactored superset functions in a way to maintain compatibility with the existing behavior This refactoring initially covers MMC/SD card loading (RAW and FS-based).

2019-01-01SPL: Add HAB image authentication to FITYe Li
Introduce two board level callback functions to FIT image loading process, and a SPL_FIT_FOUND flag to differentiate FIT image or RAW image. Implement functions in imx common SPL codes to call HAB funtion to authenticate the FIT image. Generally, we have to sign multiple regions in FIT image: 1. Sign FIT FDT data (configuration) 2. Sign FIT external data (Sub-images) Because the CSF supports to sign multiple memory blocks, so that we can use one signature to cover all regions in FIT image and only authenticate once. The authentication should be done after the entire FIT image is loaded into memory including all sub-images. We use "-p" option to generate FIT image to reserve a space for FIT IVT and FIT CSF, also this help to fix the offset of the external data (u-boot-nodtb.bin, ATF, u-boot DTB). The signed FIT image layout is as below: -------------------------------------------------- | | | | | | | | | FIT | FIT | FIT | | U-BOOT | ATF | U-BOOT | | FDT | IVT | CSF | | nodtb.bin | | DTB | | | | | | | | | -------------------------------------------------- Signed-off-by: Ye Li <ye.li@nxp.com> Reviewed-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2018-09-25spl: Weed out CONFIG_SYS_TEXT_BASE usageMarek Vasut
The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location is available and can be corrupted by loading ie. uImage or fitImage headers there. Sometimes it could be beneficial to load the headers elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we still want to parse the image headers in some local onchip memory to ie. extract firmware from that image. Add the possibility to override the location where the headers get loaded by introducing new function, spl_get_load_buffer() which takes two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the data that are to be loaded there -- and returns a valid buffer address or hangs the system. The default behavior is the same as before, add the offset to CONFIG_SYS_TEXT_BASE and return that address. User can override the weak spl_get_load_buffer() function though.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-05-17SPL: FIT: allow loading multiple imagesAndre Przywara
So far we were not using the FIT image format to its full potential: The SPL FIT loader was just loading the first image from the /images node plus one of the listed DTBs. Now with the refactored loader code it's easy to load an arbitrary number of images in addition to the two mentioned above. As described in the FIT image source file format description, iterate over all images listed at the "loadables" property in the configuration node and load every image at its desired location. This allows to load any kind of images: - firmware images to execute before U-Boot proper (for instance ARM Trusted Firmware (ATF)) - firmware images for management processors (SCP, arisc, ...) - firmware images for devices like WiFi controllers - bit files for FPGAs - additional configuration data - kernels and/or ramdisks The actual usage of this feature would be platform and/or board specific.

Currently the SPL FIT loader always looks only for the first image in the /images node a FIT tree, which it loads and later executes. Generalize this by looking for a "firmware" property in the matched configuration subnode, or, if that does not exist, for the first string in the "loadables" property. Then using the string in that property, load the image of that name from the /images node. This still loads only one image at the moment, but refactors the code to allow extending this in a following patch. To simplify later re-usage, we also generalize the spl_fit_select_index() function to not return the image location, but just the node offset.

2017-05-17SPL: FIT: refactor FDT loadingAndre Przywara
Currently the SPL FIT loader uses the spl_fit_select_fdt() function to find the offset to the right DTB within the FIT image. For this it iterates over all subnodes of the /configuration node in the FIT tree and compares all "description" strings therein using a board specific matching function. If that finds a match, it uses the string in the "fdt" property of that subnode to locate the matching subnode in the /images node, which points to the DTB data. Now this works very well, but is quite specific to cover this particular use case. To open up the door for a more generic usage, let's split this function into: 1) a function that just returns the node offset for the matching configuration node (spl_fit_find_config_node()) 2) a function that returns the image data any given property in a given configuration node points to, additionally using a given index into a possbile list of strings (spl_fit_select_index()) This allows us to replace the specific function above by asking for the image the _first string of the "fdt" property_ in the matching configuration subnode points to. This patch introduces no functional changes, it just refactors the code to allow reusing it later. (diff is overly clever here and produces a hard-to-read patch, so I recommend to throw a look at the result instead).

2016-07-22spl: fit: Fix the number of bytes read in raw modeLokesh Vutla
In raw mode a full sector is to be read even if image covers part of a sector. Number of sectors are calculated as ROUND_UP(size)/sec_size by FIT framework. This calculation assumes that image is at the 0th offset of a sector, which is not true always in FIT case. So, include the image offset while calculating number of sectors.

2016-07-14spl: fit: add support for post-processing of imagesDaniel Allred
The next stage boot loader image and the selected FDT can be post- processed by board/platform/device-specific code, which can include modifying the size and altering the starting source address before copying these binary blobs to their final destination. This might be desired to do things like strip headers or footers attached to the images before they were packaged into the FIT, or to perform operations such as decryption or authentication. Introduce new configuration option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this feature. If enabled, a platform-specific post-process function must be provided.

2016-06-04spl: fit: Fix non-matching DT names console outputAndreas Dannenberg
When no DTB can be matched successfully to the board that's being used a list of available FIT-embedded DTBs will be output to the console for diagnostic purposes. But rather than the contents of the "description" FDT property a non-existent property was accessed and as a result "NULL" was output instead of the actual name(s) of the DTB(s). Fix this issue by using the correct property which is also the exact same property that's used earlier during the actual board matching process. Signed-off-by: Andreas Dannenberg <dannenberg@ti.com>
