Using romparse to generating I2C boot code for 6678

I cannot find any documentation on how to use romparse to generate the file to be written to the i2c EEPROM for booting the 6678.

sprugy5b just says "Romparse is used to append the boot parameter to boot table or a boot configuration table", but no indication what the input is, or what the command line flags actually mean.

    More to the point, however, I would like to see a clear description of how the ROM bootloader parses the contents of the I2C EEPROM when you are booting in Master I2C mode.  There is a description of the boot parameter table in sprugy5b section 3.5.2, but that doesn't say anything about where to put the program itself. Reading through the EEPROM file for the standard IBL provided with the 6678 EVM, I can see 8 boot parameter tables, but then what follows does not appear to be a boot table.  I would expect to see a 32-bit entry point, followed by length, start address and data, but how does the RBL know where this table starts?
