The P100a platform uses different register access patterns and speed encoding compared to previous generation hardware (Yellow Carp,etc.) Key differences include: 1. Different XPCS window offset calculation due to changed memory mapping 2. 2.5G speed uses XGMII mode (ss=0x06) instead of GMII (ss=0x02) 3. Extended port speed bits (6-bit instead of 5-bit) for 5G support The series is organized as follows: Patch 1: Defines macros for MAC version numbers and speed select values to replace hardcoded magic numbers Patch 2: Adds the core P100a platform support with PCI ID, register configuration, and version-specific behavior Tested on AMD P100a platform verifying: - 10G/2.5G/1G/100M link establishment - PHY initialization and auto-negotiation - No register access errors ==================== Link: https://patch.msgid.link/20260302044409.1388430-1-Raju.Rangoju@amd.com Signed-off-by: Paolo Abeni --- d8103bfe41eeb8b6842672502a0025b7278931a8
