Apparently this one:

14fa2dd00f4f996c9583c8fba63bfa03f5025ec3

Looks like this is what has helped:

  /* TWL6030 */
+#ifndef CONFIG_SPL_BUILD
  #define CONFIG_TWL6030_POWER           1
+#endif

On a closer look, it looks like this may not be the case for OMAP3.
CONFIG_TWL4030_POWER seems to be defined even for SPL. So, I think we
need to do something like this:

#if defined(CONFIG_TWL6030_POWER) || defined(CONFIG_TWL4030_POWER) || 
defined(CONFIG_EEPROM)

i2c_init();

#endif

If you agree, I will do this change in v2.

BTW, I think you can also remove CONFIG_TWL4030_POWER from SPL. As we
continue to boot from the same media where ROM code picked up SPL from,
the regulators should be in proper condition.
