2025-06-25lmb: replace lmb_reserve() and lmb_alloc_addr() API'sSughosh Ganu
There currently are multiple allocation API's in the LMB module. There are a couple of API's for allocating memory(lmb_alloc() and lmb_alloc_base()), and then there are two for requesting a reservation for a particular memory region (lmb_reserve() and lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will cater to all types of allocation requests and replace lmb_reserve() and lmb_alloc_addr() with the new API. Moreover, the lmb_reserve() API is pretty similar to the lmb_alloc_addr() API, with the one difference being that the lmb_reserve() API allows for reserving any address passed to it -- the address need not be part of the LMB memory map. The lmb_alloc_addr() does check that the address being requested is actually part of the LMB memory map. There is no need to support reserving memory regions which are outside the LMB memory map. Remove the lmb_reserve() API functionality and use the functionality provided by lmb_alloc_addr() instead. The lmb_alloc_addr() will check if the requested address is part of the LMB memory map and return an error if not.

2025-06-24boot/image-android: Workaround kernel/ramdisk invalid addrGeorge Chan
Some androidboot image have invalid kernel/ramdisk load addr, force to ignore those value and use loadaddr instead. There is a concern on exposing the whole memory to image loading is dangerous. Also, since it's not always possible to change the load addr by repacking the boot.img (mainly due to AVB signature mismatch), we need a way to use kernel_addr_r and ramdisk_addr_r.

2025-06-20bootstd: Fix incorrect struct name in bootmeth_setup_iter_order()Sam Protsenko
There is no such thing as struct bootmeth, it's probably a typo. This issue doesn't affect the execution as it's a pointer, and pointer sizes are the same for all data types. But it can be confusing, so make it struct udevice, as it should be. Fixes: a950d31abe98 ("bootstd: Add the bootmeth uclass and helpers") Signed-off-by: Sam Protsenko <[email protected]>
2025-06-20bootstd: Probe bootmeth devices for bootmeths env varSam Protsenko
Specifying efi_mgr in 'bootmeths' environment variable leads to NULL pointer dereference when 'bootflow scan' is executed, with call trace like this: priv->fake_dev // NULL pointer dereference .read_bootflow = efi_mgr_read_bootflow() bootmeth_get_bootflow() bootflow_check() bootflow_scan_first() do_bootflow_scan() 'bootflow scan -l' That happens because in case when 'bootmeths' env var is defined the bootmeth_efi_mgr driver is not probed, and the memory for its private data isn't allocated by .priv_auto. In case when 'bootmeths' env var is not defined, the std->bootmeth_count is 0, and the execution flow in bootmeth_setup_iter_order() takes "no ordering" path, which in turn runs uclass_get_device_by_seq() -> ... -> device_probe(), so issue isn't present there. But when 'bootmeths' is defined and contains efi_mgr, the std->bootmeth_count > 0, so bootmeth_setup_iter_order() follows the "we have an ordering" path, where devices are not probed. In other words: 'bootmeths' defined 'bootmeths' not defined -------------------------------------------------------- priv == NULL priv != NULL ^ ^ | device_alloc_priv() no probe device_of_to_plat() ^ device_probe() | uclass_get_device_tail() dev = order[i] uclass_get_device_by_seq() ^ ^ | have an ordering | no ordering +----------------+---------------+ | bootmeth_setup_iter_order() bootflow_scan_first() do_bootflow_scan() Add an explicit device_probe() call in "we have an ordering" case to fix the issue.

2025-06-18Merge patch series "bootstd: New bootmeth for RAUC A/B systems"Tom Rini
Martin Schwan <[email protected]> says: This series implements a new bootmeth for RAUC A/B systems. RAUC (Robust Auto Update Controller) is a lightweight update client, providing "Safe and Secure OTA Updates for Embedded Linux". See the following links for more information about RAUC: https://rauc.io/ https://rauc.readthedocs.io/en/latest/ PHYTEC uses RAUC in its Yocto based distribution "Ampliphy" as the default way of updating embedded devices based on PHYTEC hardware. So far, the logic selecting the correct partitions and files to boot was being implemented in the U-Boot environment. While this is a straightforward way to do it, adding and supporting new platforms became somewhat tedious and is platform-specific. The introduction of U-Boot's "Standard Boot" provided a convincing alternative, promising a simpler and more portable way of booting, even for RAUC systems. This led me to implement a new bootmeth supporting RAUC A/B systems. Note, that this new bootmeth is not proprietary to PHYTEC products and is designed to work on other hardware with a RAUC A/B system, too. The bootmeth currently only supports symmetric A/B partitioning layouts. E.g. A/rescue is not (yet) supported. The partition indexes and default slot tries can be specified via configuration options. For now, the bootmeth_rauc uses a similar approach for loading the Kernel and device tree as the bootmeth_script, in that it requires a FIT containing a U-Boot script loading the desired distro. It could be possible to support booting without a script and load the Kernel and DT directly with this bootmeth, but I found the script method to be very flexible for now, in letting the distro decide what to load. The bootmeth_rauc was tested on a phyBOARD-Pollux i.MX8M Plus [1] with BSP-Yocto-Ampliphy-i.MX8MP-PD24.1.2 [2]. Supported boot devices are currently only MMC devices, but it should be possible to add SPI flashes in the future. To test this patch stack with PHYTEC's phyBOARD-Pollux i.MX8M Plus board, you need to adjust the boot files to include the boot.scr.uimg containing the distro's boot script and set "optargs" to "${raucargs}" in it. Also disable any legacyboot in the U-Boot environment and simply boot with Standard Boot: bootmeth order rauc bootflow scan -lb [1]: https://www.phytec.eu/en/produkte/single-board-computer/phyboard-pollux/ [2]: https://download.phytec.de/Software/Linux/BSP-Yocto-i.MX8MP/BSP-Yocto-Ampliphy-i.MX8MP-PD24.1.2/ Link: https://lore.kernel.org/r/[email protected] [trini: Don't enable by default]

2025-06-12fdt: Make sure there is no stale initrd leftRichard Weinberger
Although if we don't setup an initrd, there could be a stale initrd setting from the previous boot firmware in the live device tree. So, make sure there is no setting left if we don't want an initrd. This can happen when booting on a Raspberry Pi. The boot firmware can happily load an initrd before us and configuring the addresses in the live device tree we get handed over. Especially the setting `auto_initramfs` in config.txt is dangerous. When enabled (default), the firmware tries to be smart and looks for initramfs files.

2025-05-30image: android: fix ramdisk default addressEddie Kovsky
Commit 21e7fa0e3ac5 ("image: android: handle ramdisk default address") changed the default behavior for header versions less than or equal to 2. The ramdisk address (img_data.ramdisk_ptr) is only assigned to *rd_data if the physical load address (img_data.ramdisk_addr) is equal to 0 or the Android default ramdisk address. /* Ramdisk can be used in-place, use current ptr */ if (img_data.ramdisk_addr == 0 || img_data.ramdisk_addr == ANDROID_IMAGE_DEFAULT_RAMDISK_ADDR) { *rd_data = img_data.ramdisk_ptr; } else { ramdisk_ptr = img_data.ramdisk_addr; *rd_data = ramdisk_ptr; memcpy((void *)(ramdisk_ptr), (void *)img_data.ramdisk_ptr, img_data.ramdisk_size); } When the img_data.ramdisk_addr and the img_data.kernel_addr are the same *rd_data needs to be assigned to the ramdisk address (ramdisk_ptr), not the physical address (ramdisk_addr). As a result of the current behavior, we can no longer boot a kernel on the Renesas R-Car S4 board. Add an additional check to the if clause so that the ramdisk address is assigned when the kernel address and the ramdisk address are the same, restoring the previous default behavior.

2025-05-30bootm: Fix bmi->images pointer not initialized in some casesBenjamin ROBIN
When building with only bootz command, without bootm, images pointer inside bootm_info structure is not initialized. And since this structure is stored in stack, the generated error is kind of random, but most of the time this will generate: "ramdisk - allocation error". Also, after analysis, this problem could occur with the command booti, if the command bootm is disabled. Currently bootm_init() is called by: do_bootz(), do_bootm(), do_booti() and by do_stm32prog(). And all of these commands execute bootm_run_states() which access the images pointer stored into bootm_info structure. So, to fix this issue, just do the assignment unconditionally.
