Hello All,
I searched over the mailing list and did not find a solution for OMAP1510/5910 to use more than 32 MB.

Has anyone made 64MB work on 1510/5910?
Voiceblue board comes with 64MB RAM, however USB host doesn't work, because its driver code maps only 32MB staticaly.
Best regards,

As I recall, this is possible, but undocumented. It will work, depending on the particular SDRAM you have.
Set the SDRAM_TYPE field of the EMIFF_SDRAM_CONFIG register to 1101. Even though the TRM (or SPRU673) says this setting is for 8-bit data bus width, it works for our 16-bit bus configuration, and I can access 64MB.
Perhaps any listening TI folks could elaborate...
