That configuration runs out of internal SRAM and, as a result, this
configuration needs to be recalibrated.
2013-8-31: SDRAM configuration and RAM test usage are documented,
but only partially functional. SDRAM is accessible but many regions
on the SDRAM fail the RAM test. Most likely there is some error in
the SDRAM timing configuration. I am also seeing occasional crashes
involving unexpected interrupts and the UART when running the RAM
test. Not sure what to make of that yet
2013-8-3: SDRAM configuration and RAM test usage have been verified
and are functional. I not some issues now; Occassionally, SDRAM is
not functional on initial boot. Or is initially not functional but
improves with accesses. Clearly, more work needs to be done.
Here is another strange observation: SDRAM accesses tend to
generate occasional spurious interrupts! No idea why.
