[PATCH v7 04/11] ARM: dts: aspeed: anacapa: Add additional EEPROM node for SCM

[Colin Huang via B4 Relay]

From: Colin Huang <u8813345 at gmail.com>

The SCM FRU EEPROM I2C address differs between SCM revisions:
- Rev B uses address 0x50
- Rev C/D/E/F and later use address 0x51

Add an additional AT24C128 EEPROM node at 0x51 on i2c9 so the same
device tree can support multiple SCM revisions.
