2022-09-29treewide: Drop bootm_headers_t typedefSimon Glass1-3/+3
This is not needed and we should avoid typedefs. Use the struct instead. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-11-11Remove LYNX KDI remaindersThomas Huth1-1/+0
The last board that used to set CONFIG_LYNXKDI has been removed in commit 242836a893ae ("powerpc: ppc4xx: remove pcs440ep support"), doc/README.lynxkdi only talks about a MPC8260 board being supported, and the mpc8260 support has been removed four years ago in commit 2eb48ff7a210d ("powerpc, 8260: remove support for mpc8260") already, and common/lynxkdi.c only consists of an "#error" statement these days, so it seems like the LYNX KDI code is dead code nowadays. Let's remove it now. Signed-off-by: Thomas Huth <thuth@redhat.com>
2020-12-04bootm: Support string substitution in bootargsSimon Glass1-4/+10
In some cases it is necessary to pass parameters to Linux so that it will boot correctly. For example, the rootdev parameter is often used to specify the root device. However the root device may change depending on whence U-Boot loads the kernel. At present it is necessary to build up the command line by adding device strings to it one by one. It is often more convenient to provide a template for bootargs, with U-Boot doing the substitution from other environment variables. Add a way to substitute strings in the bootargs variable. This allows things like "rootdev=${rootdev}" to be used in bootargs, with the ${rootdev} substitution providing the UUID of the root device. For example, to substitute the GUID of the kernel partition: setenv bootargs "console=/dev/ttyS0 rootdev=${uuid}/PARTNROFF=1 kern_guid=${uuid}" part uuid mmc 2:2 uuid bootm This is particularly useful when the command line from another place. For example, Chrome OS stores the command line next to the kernel itself. It depends on the kernel version being used as well as the hardware features, so it is extremely difficult to devise a U-Boot script that works on all boards and kernel versions. With this feature, the command line can be read from disk and used directly, with a few substitutions set up. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Allow updating the bootargs in a bufferSimon Glass1-0/+16
At present we only support updating the 'bootargs' environment variable. Add another function to update a buffer instead. This will allow zimage to use this feature. Also add a lot more tests to cover various cases. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Update bootm_process_cmdline_env() to use flagsSimon Glass1-2/+9
At present only one transformation is supported: making the Linux console silent. To prepare for adding more, convert the boolean parameter into a flag value. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Add a bool parameter to bootm_process_cmdline_env()Simon Glass1-1/+2
This function will soon do more than just handle the 'silent linux' feature. As a first step, update it to take a boolean parameter, indicating whether or not the processing is required. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Rename fixup_silent_linux()Simon Glass1-2/+2
We want to add more processing to this function. Before doing so, rename it to bootm_process_cmdline_env(), which is more generic. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Update fixup_silent_linux() to return an errorSimon Glass1-2/+9
At present this function fails silently on error. Update it to produce an error code. Report this error to the user and abort the boot, since it likely will prevent a successful start. No tests are added at this stage, since additional refactoring is taking place in subsequent patches. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-04bootm: Add tests for fixup_silent_linux()Simon Glass1-0/+3
This function currently has no tests. Export it so that we can implement a simple test on sandbox. Use IS_ENABLED() to remove the unused code, instead #ifdef. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-10-14bootm: add {arch,board}_preboot_os() to bootm.hHeinrich Schuchardt1-0/+10
Functions that are used in multiple C modules should be defined in an include. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Michael Walle <michael@walle.cc>
2020-07-17common: bootm: add checks to verify if ramdisk / fdtimage overlaps OS imageTero Kristo1-1/+2
These cases are typically fatal and are difficult to debug for random users. Add checks for detecting overlapping images and abort if overlap is detected. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass1-7/+9
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29common: Move bootm_decomp_image() to image.c (as image_decomp())Julius Werner1-17/+0
Upcoming patches want to add decompression to use cases that are no longer directly related to booting. It makes sense to retain a single decompression routine, but it should no longer be in bootm.c (which is not compiled for all configurations). This patch moves bootm_decomp_image() to image.c and renames it to image_decomp() in preparation of those upcoming patches.

2019-05-09Make FIT support really optionalFabrice Fontaine1-0/+2
Due to some mistakes in the source code, it was not possible to really turn FIT support off. This commit fixes the problem by means of the following changes: - Enclose "bootm_host_load_image" and "bootm_host_load_images" between checks for CONFIG_FIT_SIGNATURE, in common/bootm.c. - Enclose the declaration of "bootm_host_load_images" between checks for CONFIG_FIT_SIGNATURE, in common/bootm.h. - Condition the compilation and linking of fit_common.o fit_image.o image-host.o common/image-fit.o to CONFIG_FIT=y, in tools/Makefile.

2018-06-03Define board_quiesce_devices() in a shared locationSimon Glass1-0/+2
This undocumented function relies on arch-specific code to declare a nop weak version. Add the weak function in common code instead to avoid having to duplicate the same function in each arch. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2015-05-28Combine bootm_find_<thing> functions togetherKarl Apsite1-1/+1
bootm_find_ramdisk_fdt() renamed to bootm_find_images() for readability. The function bootm_find_ramdisk_fdt() appears to be a simple wrapper for bootm_find_ramdisk(), bootm_find_fdt(), and now bootm_find_loadables(). I didn't see any other callers entering a bootm_find<thing>, so removing the wrapper, and condensing these together hopefully makes the code a little simpler.

2014-08-30cmd_bootm.c: Add 'booti' for ARM64 Linux kernel ImagesTom Rini1-1/+1
The default format for arm64 Linux kernels is the "Image" format, described in Documentation/arm64/booting.txt. This, along with an optional gzip compression on top is all that is generated by default. The Image format has a magic number within the header for verification, a text_offset where the Image must be run from, an image_size that includes the BSS and reserved fields. This does not support automatic detection of a gzip compressed image. Signed-off-by: Tom Rini <trini@ti.com>

2014-06-19bootm: Split out code from cmd_bootm.cSimon Glass1-0/+55
This file has code in three different categories: - Command processing - OS-specific boot code - Locating images and setting up to boot Only the first category really belongs in a file called cmd_bootm.c. Leave the command processing code where it is. Split out the OS-specific boot code into bootm_os.c. Split out the other code into bootm.c Header files and extern declarations are tidied but otherwise no code changes are made, to make it easier to review.
