Help text

If enabled, the driver auto-detects if a chip in the SPD address range is compliant to the SPD51888 standard and auto-instantiates if that is the case. If disabled, SPD5118 compliant devices have to be instantiated by other means. On X86 systems with DMI support this will typically be done from DMI DDR detection code in the I2C SMBus subsystem. Devicetree based systems will instantiate attached devices if the DIMMs are listed in the devicetree file.

Disabling the detect function will speed up boot time and reduce the risk of mis-detecting SPD5118 compliant devices. However, it may result in missed DIMMs under some circumstances.

If unsure, say Y.
