[U-Boot] Help with ppc460sx i2c_transfer

I'm having a difficult time figuring out why I'm failing to get an ACK response generated when running the /drivers/i2c/ppc4xx_i2c.c -> i2c_transfer function. I'm using the same values as a reference boot loader from a while back (2007). Here is my I2C configurations: 231 /* SPD i2c spd addresses

[U-Boot] Upgrading PowerPC 4xx to v2013.01

I've been tasked with porting U-Boot from v1.1.5 to v2013.01 for a custom board based off PPC460SX (AMCC Eiger board which is no longer supported). I'm trying to understand what's going on with my current setup. I'm able to load the u-boot.bin and can see that it's in the correct address location.
