The address space of possible SPD-EEPROMs 0x50..0x53 on the SMBus interface is per default write-protected in FSP. This avoids that an SPD-EEPROM on a DRAM module gets overwritten by the host. On mc_ehl1, memory-down configuration is used and there is no SPD EEPROM available. Nevertheless, there is a general purpose EEPROM on the same address available which needs to stay writeable. This patch disables the default-enabled write protect feature for the SPD-EEPROM addresses just for mc_ehl1. Test=Boot into Linux and make sure a write access into the EEPROM is possible.
