sysinfo: tq_eeprom: new driver

2026-06-05T15:56:32Z

Introduce a sysinfo driver that can be instantiated from the device, which will provide information from the EEPROM found on all TQ-Systems SoMs. Signed-off-by: Nora Schiffer Signed-off-by: Max Merchel Reviewed-by: Simon Glass Signed-off-by: Alexander Feilke

sysinfo: add sysinfo_get_and_detect() helper

2026-06-05T15:56:32Z

sysinfo_detect() is commonly called after sysinfo_get(). Make the API a bit more convenient to use by introducing a helper. Signed-off-by: Nora Schiffer Signed-off-by: Alexander Feilke Reviewed-by: Simon Glass

sysinfo: uclass: use sysinfo_priv size for per_device_auto

2026-06-05T15:56:32Z

Reference the struct itself for the size as it is more robust, even if it contains just a bool at the moment. Signed-off-by: Nora Schiffer Reviewed-by: Simon Glass Signed-off-by: Alexander Feilke

smbios: add support for dynamic generation of Type 16 table

2026-02-18T14:27:51Z

This commit implements SMBIOS Type 16 (Physical Memory Array) generation with a hybrid approach supporting both: 1. Explicit definition via Device Tree 'smbios' node: Child node under '/smbios/smbios/memory-array' will be used to populate as individual Type 16 structure directly. - Properties follow SMBIOS field names with lowercase letters and hyphen-separated words (e.g., 'memory-error-correction', 'maximum-capacity', 'extended-maximum-capacity', etc.). - This method supports precise platform-defined overrides and system descriptions. 2. Fallback to automatic DT-based discovery: If child node under '/smbios/smbios/memory-array' does not exist, the implementation will: - Scan all top-level 'memory@' nodes to populate Type 16 structure with inferred size and location data. - Scan nodes named or marked as 'memory-controller' and parse associated 'dimm@' subnodes (if present) to extract DIMM sizes and map them accordingly. This dual-mode support enables flexible firmware SMBIOS reporting while aligning with spec-compliant naming and runtime-detected memory topology. Type 16 support is under GENERATE_SMBIOS_TABLE_VERBOSE to avoid increasing rom size for those platforms which only require basic SMBIOS support.

sysinfo: Add driver for IOT2050 boards

2025-02-28T14:41:54Z

This brings a sysinfo driver and DT entry for the IOT2050 board series. It translates the board information passed from SE-Boot to SPL into values that can be retrieved via the sysinfo API. Will is already used to fill the SMBIOS table when booting via EFI. Signed-off-by: Baocheng Su Signed-off-by: Li Hua Qian [Jan: split-off as separate patch, cleanup] Signed-off-by: Jan Kiszka

sysinfo: Add API for accessing data elements

2025-02-28T14:41:54Z

This commit introduces a new API to the sysinfo module, allowing access to data elements. This is particularly useful for handling data with multiple instances, such as MAC addresses. Signed-off-by: Baocheng Su

sysinfo: Add sysinfo driver and data structure for smbios

2025-01-14T20:29:29Z

Add sysinfo driver to retrieve smbios information (Type 4 and 7). So that the smbios library can use it for getting values from the hardware platform instead of device tree. Signed-off-by: Raymond Mao

sysinfo: Add sysinfo API for accessing data area

2025-01-14T20:29:29Z

Add interface for sysinfo to access a data area from the platform. This is useful to save/read a memory region of platform-specific data. Signed-off-by: Raymond Mao

dm: sysinfo: Shorten the SYSINFO_ID prefix

2024-11-17T19:12:54Z

We are about to add a large number of new entries. Update the prefix to be a little shorter. For SMBIOS items, use SYSID_SM_ (for System Management) which is enough to distinguish it. For now at least, it seems that most items will be for SMBIOS. Signed-off-by: Simon Glass Acked-by: Raymond Mao
