2025-01-14fdt_support: board_fdt_chosen_bootargs() should return const char*Dmitry Rokosov
It should be structured this way to demonstrate to the caller that freeing the return value is unnecessary and that the caller cannot modify it. The function fdt_setprop() includes a parameter with a const char* prototype, so it is better to use the const qualifier.

2024-12-12boot: fdt: Handle already reserved memory in boot_fdt_reserve_region()Sam Protsenko
The boot_fdt_add_mem_rsv_regions() function can be called twice, e.g. first time during the board init (as a part of LMB init), and then when booting the OS with 'booti' command: lmb_add_region_flags lmb_reserve_flags boot_fdt_reserve_region boot_fdt_add_mem_rsv_regions ^ | +-----------------------+ | (1) | (2) lmb_reserve_common image_setup_linux lmb_init ... initr_lmb do_booti board_init_r 'booti' That consequently leads to the attempt of reserving the same memory areas (described in the 'reserved-memory' dts node) in LMB. The lmb_add_region_flags() returns -EEXIST error code in such cases, but boot_fdt_reserve_region() handles all negative error codes as a failure to reserve fdt memory region, printing corresponding error messages, which are essentially harmless, but misleading. For example, this is the output of 'booti' command on E850-96 board: => booti $loadaddr - $fdtaddr ... ERROR: reserving fdt memory region failed (addr=bab00000 size=5500000 flags=2) ERROR: reserving fdt memory region failed (addr=f0000000 size=200000 flags=4) ... Starting kernel ... The mentioned false positive error messages are observed starting with commit 1d9aa4a283da ("lmb: Fix the allocation of overlapping memory areas with !LMB_NONE"), which removes the check for the already added memory regions in lmb_add_region_flags(), making it return -1 for !LMB_NONE cases. Another commit 827dee587b75 ("fdt: lmb: add reserved regions as no-overwrite") changes flags used for reserving memory in boot_fdt_add_mem_rsv_regions() from LMB_NONE to LMB_NOOVERWRITE. So together with the patch mentioned earlier, it makes lmb_add_region_flags() return -1 when called from boot_fdt_reserve_region(). Since then, the different patch was implemented, returning -EEXIST error code in described cases, which is: lmb: Return -EEXIST in lmb_add_region_flags() if region already added Handle -EEXIST error code as a normal (successful) case in lmb_reserve_flags() and don't print any messages.

The current implementation is reading the whole partition for boot and vendor_boot image which can be long following the size of the partition or the time to read blocks (driver/SoC specific). For example with mediatek mt8365 EVK board, we have a 64MiB boot partition and the boot image flashed in this partition is only 42MiB. It takes ~8-9 secs to read the boot partition. Instead we can retrieved the boot image and vendor boot image size with these new functions: - android_image_get_bootimg_size - android_image_get_vendor_bootimg_size Use these information and read only the necessary. By doing this with mt8365 EVK board, we read boot image in ~5 secs.

2024-10-27Merge patch series "Implement ACPI on aarch64"Tom Rini
Patrick Rudolph <[email protected]> says: Based on the existing work done by Simon Glass this series adds support for booting aarch64 devices using ACPI only. As first target QEMU SBSA support is added, which relies on ACPI only to boot an OS. As secondary target the Raspberry Pi4 was used, which is broadly available and allows easy testing of the proposed solution. The series is split into ACPI cleanups and code movements, adding Arm specific ACPI tables and finally SoC and mainboard related changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the mandatory ACPI tables are supported, allowing to boot into Linux without errors. The QEMU SBSA support is feature complete and provides the same functionality as the EDK2 implementation. The changes were tested on real hardware as well on QEMU v9.0: qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \ -pflash secure-world.rom \ -pflash unsecure-world.rom qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \ -smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \ -dtb bcm2711-rpi-4-b.dtb -nographic Tested against FWTS V24.03.00. Known issues: - The QEMU rpi4 support is currently limited as it doesn't emulate PCI, USB or ethernet devices! - The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly cache related). - PCI on RPI4 isn't working on real hardware since the pcie_brcmstb Linux kernel module doesn't support ACPI yet.

I enabled IMX_HAB on an imx8mp board, but even though I knew about the implementation, I forgot that I had to provide a sane value for SPL_LOAD_FIT_ADDRESS. The help text for IMX_HAB doesn't mention this implicit requirement, and there's no build-time warning; the default 0x0 value just ends up being returned from board_spl_fit_buffer_addr(), obviously resulting in a non-booting board. The existing imx8m* board configs that set a non-zero value currently all use 0x44000000. The actual value doesn't matter too much, but 0 is always wrong for imx8m platforms. So just use 0x44000000 as default for those platforms. Signed-off-by: Rasmus Villemoes <[email protected]>

The two tools that create android boot images, mkbootimg and the fastboot client, set the kernel address by default to 0x11008000. U-boot always honors this field, and will try to copy the ramdisk to whatever value is set in the header, which won't be mapped to the actual RAM on most platforms, resulting in the kernel obviously not booting. All the targets in U-Boot right now will download the android boot image to CONFIG_SYS_LOAD_ADDR, which means that it will already have been downloaded to some location that is suitable to use the ramdisk in-place for header version 0 to 2. For header version 3 and later, the ramdisk can't be used in-place to use ramdisk_addr_r in this case.

It's really helpful to have the ability to dump BCB block for debugging A/B logic on the board supported this partition schema. Command 'bcb ab_dump' prints all fields of bootloader_control struct including slot_metadata for all presented slots. Output example: ===== > board# bcb ab_dump ubi 0#misc > Read 512 bytes from volume misc to 000000000bf07580 > Read 512 bytes from volume misc to 000000000bf42f40 > Bootloader Control: [misc] > Active Slot: _a > Magic Number: 0x42414342 > Version: 1 > Number of Slots: 2 > Recovery Tries Remaining: 0 > CRC: 0x2c8b50bc (Valid) > > Slot[0] Metadata: > - Priority: 15 > - Tries Remaining: 0 > - Successful Boot: 1 > - Verity Corrupted: 0 > > Slot[1] Metadata: > - Priority: 14 > - Tries Remaining: 7 > - Successful Boot: 0 > - Verity Corrupted: 0 ==== The ab_dump command allows you to display ABC data directly on the U-Boot console. During an A/B test execution, this test verifies the accuracy of each field within the ABC data.
