The last two days I bisected within the range r484..r647, with local  
patch for OSX host support. I gave up this endeavor because too many  
commits didn't compile for me at all (including assumed-good r484).
Some worked with powerpc-gnu-linux-* -> powerpc-elf-* symlinks, but  
most failed with type errors. Some compiled but found no secondary  
bootloader. Log attached.

Bisecting did however remind me of a change of the 'ofmem'  
implementation (r521). That might be an explanation why the address  
changed from 0x07d00000 to 0x07f00000, I guess?

As for the problematic memset, is there any way I could try out if  
this is the same issue as with cmd646 or not?

Happy Holidays everyone,

Andreas
