As far as I know it does not. The EEPROM is only read to tell the
boards apart, so I will drop the i2c2 and EEPROM tags in v3 and keep
the PMIC, whose rails are set before DRAM can be brought up, and the
SPI NOR flash, which the BootROM can boot from.

Yixun, is there a public description of the BootROM boot flows, or of
which peripherals it sets up in each? That would give a clear basis
for which nodes to tag.

Thanks,
