 a generic u-boot (arm) and generic arm linux kernel would be
sufficient (one that supports at least a generic 16550 uart would do)

 that would be enough to test the devicetree overlay code in a
*generic* way (which it has to be anyway).

 reading the EEPROM *has* to be a generic processor-independent
action, because you can have literally any processor type (or not even
a processor - even an FPGA) reading the I2C 0x51 addressed EEPROM.
