[PATCH v2 1/4] boot: pxe_utils: Add fallback support
by Martyn Welch 15 Oct '24

15 Oct '24

When configured correctly, we can detect when boot fails after the boot process has been handed over to the kernel through the use of U-Boot's bootcount support. In some instances, such as when we are performing atomic updates via a system such as OSTree, it is desirable to provide a fallback option so that we can return to a previous (hopefully working) state. Add a "fallback" option to the supported extlinux configuration options that points to a label like "default" so that we can utilise this in later commits.

[PATCH v2] Revert "mmc: dw_mmc: Extract FIFO data transfer into a separate routine"
by Jonas Karlman 15 Oct '24

15 Oct '24

The commit 0252924ac6d4 ("mmc: dw_mmc: Extract FIFO data transfer into a separate routine") unintentionally changed behavior of the FIFO data transfer routine. When data is read and size reaches 0 the original loop would wait on DWMCI_INTMSK_DTO or timeout. The remaining size to read and buf position is no longer tracked across dwmci_data_transfer_fifo() calls and because of this an extra call to fifo() and dwmci_fifo_ready() may now trigger a FIFO underflow timeout error and slows down FIFO reading. Buswidth = 4, clock: 50000000 Sending CMD16 Sending CMD17 dwmci_fifo_ready: FIFO underflow timeout Sending CMD16 Sending CMD18 dwmci_fifo_ready: FIFO underflow timeout Sending CMD12 ## Checking hash(es) for config config-1 ... OK This reverts commit 0252924ac6d4af69061bb9589d16b30c5bdb7178 to restore the old working behavior.

[PATCH v8 00/37] Implement ACPI on aarch64
by Patrick Rudolph 15 Oct '24

15 Oct '24

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.

[PATCH v4] rockchip: board: Increase rng-seed size to make it sufficient for modern Linux
by Alex Shumsky 15 Oct '24

15 Oct '24

Increase rng-seed size to make Linux happy and initialize rng pool instantly. Linux 5.19+ requires 32 bytes of entropy to initialize random pool, but u-boot currently provides only 8 bytes. Linux 5.18 and probably some versions before it used to require 64 bytes. Bump min value to 64 bytes to be on a safe side. Boot with 8 byte rng-seed (Linux 6.11): # dmesg | grep crng [ 12.089286] random: crng init done Boot with 32 byte rng-seed (Linux 6.11): # dmesg | grep crng [ 0.000000] random: crng init done Linux source references: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dri… https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dri… Signed-off-by: Alex Shumsky <alexthreed(a)gmail.com> Fixes: d2048bafae40 ("rockchip: board: Add board_rng_seed() for all Rockchip devices") Reviewed-by: Dragan Simic <dsimic(a)manjaro.org> --- Changes in v4: - fix typos and code style Changes in v3: - reword warning - increase default rng_seed_size to support older linux as well - reword commit message Changes in v2: - add env config knob rng_seed_size - add warning for small rng_seed_size - 12-character commit SHA in Fixes arch/arm/mach-rockchip/board.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-rockchip/board.c b/arch/arm/mach-rockchip/board.c index 3fadf7e412..ca6404776f 100644 --- a/arch/arm/mach-rockchip/board.c +++ b/arch/arm/mach-rockchip/board.c @@ -472,9 +472,18 @@ __weak int misc_init_r(void) __weak int board_rng_seed(struct abuf *buf) { struct udevice *dev; - size_t len = 0x8; + ulong len = env_get_ulong("rng_seed_size", 10, 64); u64 *data; + if (len < 64) { + /* + * rng_seed_size should be at least 32 bytes for Linux 5.19+, + * or 64 for older Linux kernel versions + */ + log_warning("Value for rng_seed_size too low (%lu) and likely insufficient for the Linux RNG initialization\n", + len); + } + data = malloc(len); if (!data) { printf("Out of memory\n"); -- 2.34.1
