Let me explain my point of view.

Doing SDRAM init very early (even in assembly code) is obvious and simple.
Just few simple writes into RAM controller registers.

But to use cache as RAM you need to program and enable MMU (again
assembly, right?). And then
one needs to program SDRAM controller (ok, this part is in C code, but
I don't see any advantage).
It's not as simple as previous solution, isn't it? And looks
overengineered to me. I prefer to keep
such low-level things simple.

Vasily
