Migrating from ppc to powerpc

2010-04-04 Thread Shawn Jin
Hi, I have a project that needs port ppc drivers to the powerpc arch. I've been searching the mailing list for some clues on what tasks they would look like and where should be the starting point. It's been quite a while since the powerpc arch started so the info is huge. The searching doesn't see

2010-04-04 Thread Sebastian Andrzej Siewior
From: Sebastian Andrzej Siewior During boot we change the mapping a few times until we have a "defined" mapping. During this procedure a small 4KiB mapping is created and after that one a 64MiB. Currently the offset of the 4KiB page in that we run is zero because the complete startup up code is i

2010-04-04 Thread Sebastian Andrzej Siewior
