With the fixup, it works. In all cases I'm aware of, the fixup is a *good* thing. Check the source to see what is being fixed up.

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

[U-Boot] I2C Register
Hi, 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. 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.

[U-Boot] FDT support in u-boot
Hi all, I am porting u-boot for ppc440 based board, board is similar to 440Gx but customized one. Requirement is to to port u-boot with DTS support. u-boot version is 2009-08 . We have implemented dts and compile it with dtc compiler.as we are using different bus instead of opb and ebc. please let me know can we bypass the fixup provided in fdt.c file __ft_board_setup() and ft_cpu_setup(). ~Ronny The INTERNET now has a personality.
