in the hardware document guide (page 410) for DDR SDRAM Memory the example

is the same for 256MB and 128Mb ?

There is no doc in the software guide for the register 0x75 ?


0x75 (SDP IO Map)  0x0A  Sets 128 Mb memory size.

0x75 (SDP IO Map)  0x0A  Sets 256 Mb memory size.


What is the correct value for 128 and for 256


Thanks for support
