Subject: ppc/85xx: Move to using fsl_setup_hose on MPC8572 DS
X-Git-Tag: v2010.03-rc1~180
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=42c01b9d1f0132a6d82e2c8333b236b1e3b0831f;p=platform%2Fkernel%2Fu-boot.git

ppc/85xx: Move to using fsl_setup_hose on MPC8572 DS

We can use fsl_setup_hose to determine if we are a agent/end-point or
a host.  Rather than using some SoC specific register we can just look
at the PCI cfg space of the host controller to determine this.
