Seems to me that it's far better to have init code in the kernel than firmware. For one example, look at the x86 video card init problem PowerPC Linux has. It's also far easier to fix/deploy Linux code than firmware code, as Li observed, and on top of that it's less work for non-UBoot firmwares in the future. -Hollis ------------------------------------------------------------------------- Take Surveys.
