Summary:

This PR updates the Wedge800CACT platform configuration by migrating from NETLAKE-1 to NETLAKE-2. The changes include adapting I2C device mappings, updating sysfs paths, and adjusting kernel configurations to align with the new hardware revision.

Kernel Configuration:

• Enabled CONFIG_SENSORS_INA2XX and CONFIG_SENSORS_SPD5118 to support NETLAKE-2 power and memory monitoring.

Platform Manager:

• Standardized CPU bus naming using the virtual bus "CPU_BUS".
• Implemented versionedPmUnitConfigs for NETLAKE-2 hardware identification.
• Updated pmUnitConfig, symbolicLinkToDevicePath, and CPU_CORE_TEMP sysfs paths for NETLAKE-2 I2C topology compatibility.

Sensor Service:

• Migrated "NETLAKE" sensor definitions and sysfs paths from Netlake-1 to Netlake-2.
• Migrated sensor definitions and optimized monitoring thresholds based on the NETLAKE-2 HW device table to ensure test stability.

Firmware Utility:

• Updated fw_util BIOS upgrade logic to support NETLAKE-2 specific flash sequences. No Changes Required:
• bsp_tests.json, fan_service.json, led_manager.json.

Test Plan:

Platform Manager:

• Executed platform_manager and platform_manager_hw_test on Wedge800CACT; all functional logs validated and tests passed.

Sensor Service:

• Verified initialization of universal and versioned sensors via sensor_service, sensor_service_hw_test, and sensor_service_client.

Similar question: I guess the patch is not compatible with NL1.0 hardware? I'm asking to evaluate when should I merge the patch..

@tao-ren
Yes, you are correct. This patch is not backward compatible with NL1.0 hardware.

There are two main reasons for this:

• Sensor Topology Differences: The sensor types and I2C mappings between NL1.0 and NL2.0 are different, requiring distinct configurations and thresholds.

• IDPROM Definition Overlap: The IDPROM definitions for both versions overlap, which makes it impossible for the software to distinguish between NL1.0 and NL2.0 hardware automatically at runtime.
