USB: EHCI: Reconciling USB register differences on MPC85xx vs MPC83xx
Srikanth Srinivasan [Wed, 2 Jul 2008 07:14:33 +0000 (02:14 -0500)]
A couple of USB register initializations had to be changed on MPC85xx
platforms.  This is due to the internal SoC buses being different on
MPC83xx SoCs vs MPC85xx SoCs.

We currently handle this via an ifdef since 83xx and 85xx are mutually
exclusive kernel builds.
