2025-01-22Merge patch series "upl: Prerequite patches for updated spec"Tom Rini
Simon Glass <[email protected]> says: The current UPL spec[1] has been tidied up and improved over the last year, since U-Boot's original UPL support was written. This series includes some prerequisite patches needed for the real UPL patches. It is split from [2] [1] https://github.com/UniversalPayload/spec/tree/3f1450d [2] https://patchwork.ozlabs.org/project/uboot/list/?series=438574&state=* Link: https://lore.kernel.org/r/[email protected]
2025-01-22emulation: Use bloblist to hold tablesSimon Glass
QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot copies out the SMBIOS tables but points directly to the ACPI ones. The ACPI tables are not aligned on a 4KB boundary, which means that UPL cannot use them directly, since it uses a reserved-memory node for the tables and that it assumed (by EDK2) to be 4KB-aligned. On x86, QEMU provides the tables in a mapped memory region and U-Boot makes use of these directly, thus making it difficult to use any common code. Adjust the logic to fit within the existing table-generation code. Use a bloblist always and ensure that the ACPI tables is placed in an aligned region. Set a size of 8K for QEMU. This does not actually put all the tables in one place, for QEMU, since it currently adds a pointer to the tables in QFW. On ARM, enable bloblist so that SMBIOS tables can be added to the bloblist.

2025-01-14Merge patch series "SMBIOS improvements"Tom Rini
Raymond Mao <[email protected]> says: Motivations for changes: Current SMBIOS library and command-line tool is not fully matching with the requirements: 1. Missing support for other mandatory types (#7, #9, #16, #17, #19). 2. Only a few platforms support SMBIOS node from the device tree. 3. Values of some fields are hardcoded in the library other than fetching from the device hardware. 4. Embedded data with dynamic length is not supported (E.g. Contained Object Handles in Type #2 and Contained Elements in Type #3) Changes: 1. Refactor the SMBIOS library and command-line tool to better align with the SMBIOS spec. 2. Create an arch-specific driver for all aarch64-based platforms to fetch SMBIOS private data from the device hardware (processor and cache). 3. Create a sysinfo driver to poppulate platform SMBIOS private data. 4. Add generic SMBIOS DTS file for arm64 platforms for those common strings and values which cannot be retrieved from the system registers. Vendors can create their own SMBIOS node using this as an example. For those boards without SMBIOS nodes, this DTS file can be included to have a generic SMBIOS information of the system. 5. Add support for Type #7 (Cache Information) and link its handles to Type #4. 6. To minimize size-growth for those platforms which have not sufficient ROM spaces or the platforms which don't need detailed SMBIOS information, new added fields are only being built when kconfig GENERATE_SMBIOS_TABLE_VERBOSE is selected. Once this patch is acceptted, subsequent patch sets will add other missing types (#9, #16, #17, #19). Tests: To test this with QEMU arm64, please follow the guide on dt_qemu.rst to get a merged DT to run with. ``` qemu-system-aarch64 -machine virt -machine dumpdtb=qemu.dtb cat <(dtc -I dtb qemu.dtb) <(dtc -I dtb ./dts/dt.dtb | grep -v /dts-v1/) \ | dtc - -o merged.dtb qemu-system-aarch64 -machine virt -nographic -bios u-boot.bin \ -dtb merged.dtb ``` Link: https://lore.kernel.org/r/[email protected]

The ST M24256E behaves as a regular M24C256, except for the E variant which uses up another I2C address for Additional Write lockable page. This page is 64 Bytes long and can contain additional data. Add entry for it, so users can describe that page in DT. Note that users still have to describe the main M24C256 area separately as that is on separate I2C address from this page. Unlike M24C32-D and M24C64-D, this part is specifically ST and does not have any comparable M24* counterparts from other vendors, hence the st, vendor prefix. Furthermore, the part name is M24256E without C between the 24 and 256, this is not a typo. Finally, there is M24C256-D part, which does contain 32 Bytes long Additional Write lockable page, which is a different part and not supported by this patch.

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.

2024-10-13misc: fuse: Update fuse driverYe Li
When OSCCA is enabled, FSB fuse shadow (offset 0x8000) access is disabled for SOC. So update the driver to read fuse from ELE API. The ELE has supported to read all shadow fuses like FSB, reuse the table of FSB for the word index used by ELE API. Add ELE shadow fuse read and write to current ELE fuse driver. But when LC is OEM closed, the ELE read/write shadow fuse APIs are forbidden. Reading from any fuse will return error. This causes problem to u-boot which must read out some fuse no matter whatever LC. So we have to change back to read from FSB and ELE common fuse read API. For using ELE shadow read API for development purpose like checking the ELE shadow fuse write result, user can set env variable "enable_ele_shd" to y to switch it.

2024-10-13misc: fuse: Fix FSB redundancy fuse word check and clear resYe Li
There is a bug when checking fuse word with redundancy fuse in FSB table. The redundancy fuses are combined into 4 words, so we can't directly use word index to do the check, otherwise the high 4 words will fail to match. And When calling ELE API, res parameter will pass to ELE API to get ELE response value for failure. So most of usage does not initialize this variable and print it after calling ELE API. However, when ELE API returns failure, we can't ensure this res is always set because there may be other failure like MU failure.

2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <[email protected]> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2024-03-05misc: atsha204a: fix wakeup functionMichał Barnaś
The ATSHA204A chip requires SDA line to go low for at least 60us to wake up the chip. Previous implementation did not meet this requirement due to the NAK received on bus and not sending the zeroes. The function to ignore the NAK and send bytes regardless is not supported in the u-boot making it impossible to wake up the chip this way. Instead, the bus speed, if needed, is set to lowest value and the message is sent to the address 0x0. This way, the address of zero makes the SDA line go low for about 80us, meeting the required time to wake up the chip. The zero length packet is not sent by the i2c, so the one byte is sent to the transfer function, but only the address is sent anyway. After sending the zero address, the bus speed is restored to the previous value if it was slowed down to wake up the chip. Signed-off-by: Michał Barnaś <[email protected]>

In the SMBIOS 3 entry point the Structure Table Maximum Size field was incorrectly named max_struct_size. A Maximum Structure Size field only exists in the SMBIOS 2.1 entry point and has a different meaning. Call the Structure Table Length field table_maximum_size.
