From: Holger Brunck holger.brunck@keymile.com
This board is similar to portl2, but it has the u-boot environment in a SPI NOR flash and not in an i2c eeprom like portl2 have.
Some other details: - IVM EEPROM is at adress: pca9547:70:9 - PCI is enabled - PIGGY4 is connected via MV88E6352 simple switch. There is no phy between the simple switch and the kirkwood.
