Bootloader that can also update a 24LC256 I2C serial eeprom

I don't want to re-invent the wheel.
I was wondering if anyone has a bootloader that can also update a
24LC256 I2C serial eeprom?

If I have to I'll try to make one myself.. just using the similar
intel hex format with updates for a different format and 32bit address
for the multiple 24lc256 I am updating.

I implement a mechanism in customer specific implementations of our SD/MMC and Ethernet bootloaders to handle multiple different devices including external EEPROMS, slave PICs, intelligent peripherals. I use a different type 4 record which identifies the target device (uses a type 4 address outside the range of the main PIC). This mechanism allows you to identify the device and, where necessary, the specific page in the device. This mechanism allows you to merge all hex files for different devices into a single hex file.
