Theoreticaly, there are no wait states during burst accesses,
but taking Refresh and CAS-Latency into account, you
may have an average of two clock cycles per read or write.

You could archive that by simply modifying the
kernel linker script, but the kernel stack is
usualy 8 KByte in size and the onchip SRAM is
only 4 KByte ... maybe not enough.
