The phrase "the RAM is at address 0x10000000" is bogus.

The RAM "is" where you map it. The mapping is done in  software.  The
software is implementing your design.

In other words, your design is broken when you put the RAM at such  a
strange adress instead of the natural location, starting from 0x0000.

You don't; just fix your memory map.
