Default SD read firmware.bin

[pkowald]

I need to bootloader to by default have the EEPROM 0x1FF set to 0xF0.
Such then after the bootloader has been installed it is ready to receive the code (firmware.bin)
Because if I load the firmware sketch via an ISP it kills the bootloader (this is the only option as the USB is not available on a dedicated custom board).

with the SD card and firmware.bin ready to go
Install the bootloader
When the unit kicks off, it sees the flag set and bin file present and begins the flash all in one easy hit.

Hello, we have an Arduino Mega2560 available here that comes preinstalled with a microSD flash installer while still supporting updates through SPI.
