Hi, We are migrating our PowerPC 8272-based board from 2.6.14 to 2.6.27.
One of the big changes is the need for a Device Tree for bootup. So far, my bootup looks like the below (using u-boot). I am just using arch/powerpc/boot/cuboot-824x.c and /arch/powerpc/boot/dts/mpc8272ads.dts for now. Therefore, all the settings as printed below are wrong ie. Memory, ENET0 mac, CPU clock freq, etc. When I change the settings in mpc8272ads.dts and do a fresh recompile, the settings do not change. However, if I use another cuboot*.c file, I get a different set of printed settings eg. 2 ethernet ports instead of 1. This is fine, but I don't see where in the cuboot*.c file these settings are specified. Can someone suggest where these might be? Cheers, Daniel ## Booting image at 00200000 ...
