Re: Question about DBCR0 initialization for 440

[Grant Likely <grant.likely@secretlab.ca>]

Hey John

We just discussed this on IRC.  Go ahead and generate a patch to
unconditionally turn on DBCR0[IDM] in head_44x.S.  Don't even bother
wrapping it in an #ifdef CONFIG_somthing block.  It should be safe,
but we'll throw it into -next and see if anyone complains.  If it does
cause problems, then it can be reworked to something a wee bit more
conservative.
