Hi York,

This board has soldered DDR chips. To reduce the SPL image size, use static DDR setting instead of dynamic DDR driver.

I'm just wondering - since your board supports FIT in SPL, maybe it would be good to have a binary blob with DDR RAM settings embedded into it?

Then you would be able to provide "hardcoded" SDRAM setup via it? In this way it could be easily replaceable?

Lukasz,

It sounds reasonable but doesn't work for our platforms. The limitation is the static RAM. In order to load anything, we need to have some memory. Lacking of memory is the exact reason I have to use static DDR setting. I have to make room for other drivers in SPL.
