RE: ppcboot and powerpc branch question
Wolgang, This question does pertain to the thread in question, but.. I am currently using your ELDK 4.1 Uclibc and have written various scripts that allow it to be used with buildroot makefiles.

You need to define a dts file (see the existing ones in arch/powerpc/boot/dts for examples), and set CONFIG_DEVICE_TREE to tell the wrapper which one to include. Note that this dts must have linux,network-index properties in the network nodes for the MAC addresses to be filled in, and must have /chosen/linux,stdout-path if you want output from the wrapper (useful if something goes wrong (such as insufficient memory to relocate the kernel) or if you want to edit the command line). You also need to do make zImage rather than make uImage for cuImage to be built. -Scott ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded

Yes, you can build a 'cuImage' in arch/powerpc which wraps the kernel image with a device tree and copies the bd_t data into the tree before booting. Cheers, g. -- Grant Likely, B.Sc., P.Eng.

ppcboot and powerpc branch question
hi all, After some problem with my custom board and kernel 2.6.19 about the init process, i've moved on 2.6.23 and that had fixed my problems. (related to this post : http://marc.info/?l=linuxppc-embedded&m=11960901017&w=2) Apparently it was a problem with cpm_uart on SMC1. (http://lkml.org/lkml/2007/9/23/99) the patch have been integrated in 2.6.23. Now i use this kernel and busybox works. I want to migrated my board in powerpc branch instead of ppc (i plan to use xenomai but in 2.6.23 there is only an adeos patch for piowerpc branch), but i see the use of a device tree instead of bd_t struct. I'm a bit disappointed because i also see that older u-boot (in my case ppcboot 1.1.5) aren't capable to pass dts to kernel. Is there a way to keep my old bootloader to boot a powerpc branch kernel ?
