2022-08-01	util/spd_tools/spd_gen/lp5: Remove maxSpeed for Sabrina	Karthikeyan Ramasubramanian
	Firmware component that does memory training already limits the memory controller to train at 5500 Mbps for all memory parts in Sabrina. Hence removing this interim SPD change to limit the speed. BUG=b:238074863 TEST=Build and boot to OS in Skyrim.

2022-07-19	util/spd_tools: Limit memory speed to 5500 Mbps for Sabrina	Karthikeyan Ramasubramanian
	In Sabrina platform, memory speed is limited to 5500 Mbps. Update the SPD generation tool to limit to that speed. BUG=b:238074863 TEST=Build and boot to OS in Skyrim.

2022-03-08	util/spd_tools: Encode SDRAM min cycle time (TCKMinPs)	Karthikeyan Ramasubramanian
	ADL encodes CK cycle time as tCKMin whereas Sabrina encodes WCK cycle time. Encode tCKMin as per the respective advisories. BUG=None TEST=Generate the SPD and ensure that tCKMin is encoded accordingly. Minimum CAS Latency time is also impacted and is encoded accordingly.

2022-02-17	util/spd_tools/spd_gen/lp5: Encode Bank Architecture	Karthikeyan Ramasubramanian
	ADL supports 8B Bank Architecture, whereas Sabrina supports either BG or 16B Bank Architectures depending on the speed. This influences SDRAM Density and Banks, SDRAM Addressing bytes in SPD. Encode them as per the individual SoC advisories. BUG=b:211510456 TEST=Generate SPDs for Sabrina.
