OMAP3 secure devices do not have this much public SRAM. So, the above
values wouldn't work for it. I suggest the following values:

#define CONFIG_SYS_SRAM_START              0x40208000
#define CONFIG_SYS_SRAM_SIZE               0x8000 /* 32 KB */

#define CONFIG_SPL_TEXT_BASE		CONFIG_SYS_SRAM_START
#define CONFIG_SPL_MAX_SIZE		0x7C00  /* 31 K  - set aside at least 1K 
for stack*/

best regards,
