The second Ethernet MAC (eQOS) fuse layout is changed since i.MX93 A1 following other i.MX platforms, for example i.MX8MP.
Order for A0: MAC1_ADDR[15:0] MAC1_ADDR[31:16] MAC1_ADDR[47:32] MAC2_ADDR[47:32] MAC2_ADDR[15:0] MAC2_ADDR[31:16]
Order since A1: MAC1_ADDR[15:0] MAC1_ADDR[31:16] MAC1_ADDR[47:32] MAC2_ADDR[15:0] MAC2_ADDR[31:16] MAC2_ADDR[47:32]
