net: stmmac: Add support for DWMAC5 and implement Safety Features
This adds initial suport for DWMAC5 and implements the Automotive Safety Package which is available from core version 5.10. The Automotive Safety Pacakge (also called Safety Features) offers us with error protection in the core by implementing ECC Protection in memories, on-chip data path parity protection, FSM parity and timeout protection and Application/CSR interface timeout protection. In case of an uncorrectable error we call stmmac_global_err() and reconfigure the whole core. Signed-off-by: NJose Abreu <joabreu@synopsys.com> Cc: David S.
