What is the procedure for DRAM auto-sizing ?
We want to have a single bootstream that supports 64MB, 128MB, 256MB.
So we need to have different settings for DRAM_REG ....
Can I just change DRAM_REG on the fly ??
So I set it for 256MB ... look for pattern wraparound at 64MB and 128MB and
then set DRAM_REG to 64MB setting or 128MB settings or leave it at 256MB
depending on wraparound results ....
Or do I have to do something to shutdown and restart the DRAM controller in order to
change DRAM_REG ?
