No, I beg to differ. I have ported u-boot to more then one ppc based platform. Thye do have SPD support. I ported over to the ppc750fx (with a Marvel 64360 system controller) and the 440gp based platforms --- "Eric W. Biederman" ebiederman@lnxi.com wrote:

There is also the fact that all of the platforms U-Boot runs on appear to be very simple ones. No complicated SPD base memory initialization, etc.
LinuxBIOS supports much more complicated hardware.
That is the other reason for the design skew. If you can write proper memory initialization code in a day. You can put it in your bootloader. If it takes a week or two, separating board initialization and your bootloader makes a lot more sense.
