[PATCH] USB: EHCI: Reconciling USB register differences on MPC85xx vs MPC83xx

[PATCH] USB: EHCI: Reconciling USB register differences on MPC85xx vs MPC83xx

[Kumar Gala]

From: Srikanth Srinivasan <srikanth.srinivasan@freescale.com>

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.

This is for 2.6.27 and is need for proper USB functionality of the
MPC8536DS platform that will go in via the powerpc tree in 2.6.27.
