Hi Stefan,
I am using ppc440 for customized board.
U-boot version that i am using is u-boot-2009.11. Here i am searching for the ppc4xx_i2c structure but not able to get it. on the other hand i have seen the i2c register macros used in i2c_transfer call.

I am trying to read SPD data from dimm though I2c. as the board that i am using it has different I2c register so it is difficult to match with the register used in u-boot.
Which platform are you using? PPC4xx? Or something else?
Can i get the information about /*-------------------------------------------------------------------------
| IIC Register Offsets
'-------------------------------------------------------------------------- --*/ #define IICMDBUF 0x00 #define IICSDBUF 0x02 #define IICLMADR 0x04 #define IICHMADR 0x05 #define IICCNTL 0x06 #define IICMDCNTL 0x07 #define IICSTS 0x08 #define IICEXTSTS 0x09 #define IICLSADR 0x0A #define IICHSADR 0x0B #define IICCLKDIV 0x0C #define IICINTRMSK 0x0D #define IICXFRCNT 0x0E #define IICXTCNTLSS 0x0F #define IICDIRECTCNTL 0x10
these register to that it will be easy for me to match with the register that i am using.
These defines above are not available in U-Boot any more. I switched to using a struct s while ago:
struct ppc4xx_i2c { u8 mdbuf; u8 res1; u8 sdbuf; ...
You are using PPC4xx, right?
Cheers, Stefan
