[PATCH 10/9] Small updates for Freescale MPC52xx - Late one ...

[Sylvain Munaut]

Hello

Sorry for this late one, I just got it and it belongs with the others.
I've added it to the bk tree I sent earlier ( 
bk://bkbits.246tNt.com/linux-2.5-mpc52xx-pending )
so please pull from that tree.

The unified diff along with the patch description is below.

Thanks,

    Sylvain
