Production version of the board has 64MB. Check this comment from FSL U-boot:

/* iMX25 V-1.0 has 128MB but V-1.1 has only 64MB */
#ifdef CONFIG_MX25_3DS_V10
#define PHYS_SDRAM_1_SIZE	(128 * 1024 * 1024)
#else
#define PHYS_SDRAM_1_SIZE       (64 * 1024 * 1024)
#endif

Should I use reg = <0x0 0x0>; instead and let the bootloader detect
the RAM size?
