Four I2C controllers' offset are:
#define CONFIG_SYS_FSL_I2C_OFFSET 0x118000 #define CONFIG_SYS_FSL_I2C2_OFFSET 0x118100 #define CONFIG_SYS_FSL_I2C3_OFFSET 0x119000 #define CONFIG_SYS_FSL_I2C4_OFFSET 0x119100
I will add I2C3 and I2C4.
Thanks, Shengzhou

Shengzhou,
If u-boot uses 2nd I2C controller, it is good to have some comments. Please complete with four I2C controllers' offset.

Hello Shengzhou,
T1040 has two dual I2C controller. First Dual I2C Controller : 0x1180000 (first i2c bus), 0x1181000(second I2C bus) Second Dual I2C Controller : 0x1190000 (third i2c bus), 0x1191000(fourth I2C bus)
My understanding is CONFIG_SYS_FSL_I2C_OFFSET is offset for first I2C
controller and CONFIG_SYS_FSL_I2C2_OFFSET is offset for second I2C controller.
Have you checked for dual I2C controller, CONFIG_SYS_FSL_I2C2_OFFSET
implies offset for second I2C bus, not the controller?
[Shengzhou] yes, I tested it with T1040.
Regards Priyanka

The base address of I2C2 is 0x118100 instead of 0x119000.
