Agreed. Just to add that you can see a real-world example of memory 
controller initialization code - for the Quark (used in the discontinued 
Intel Galileo development boards) at 
https://github.com/tianocore/edk2/tree/master/QuarkSocPkg/QuarkNorthCluster/MemoryInit/Pei 
.

The memory controller (or other silicon) initialization code is usually
one of the most proprietary parts of any platform firmware. It's pretty
unlikely you can get the source for it from anyone else than the
platform manufacturer, and that's assuming they're willing to let you
see it at all, even for $$$ and under strict NDA.

Dear Sir/ Madam

We are using OpenQ660 Board. we suspect that edk2 is the bootloader for the 
same. We are unable to find the ram initialization code in edk2 bootloader. 
Please help us to find the respective ram initialization code. Please do write 
back waiting for your reply.
