Memory Reference code in EDK2

ss36 — Thu, 24 Jan 2019 17:31:05 GMT

Hi ,

We are using EDK2 software with minnow board. EDK2 memory reference code is available under QuarkSOC package folder shown below.

edk2\QuarkSocPkg\QuarkNorthCluster\MemoryInit\Pei

Is the minnow board also using the Same memory reference code (Which is under Quark Folder )
We have designed a new board same like minnow boards with intel atom processor only we are changing SDRAM ( Apacer SO-DIMM) . Inorder to configure this SDRAM module anything we have to change in the Memory reference code or it will work as it is ??
Intel ATOM processor have Memory controller with mode register to configure the timing parameters and this timing parameters are available in the SPD EEPROM . Will the EDK2 will read and configure the mode registers as it is ?? OR we have to modify anything in the EDK2 memory reference code ?
