Re: [PATCH] [POWERPC] CPM1: implement GPIO LIB API

Hi Laurent,

I haven't checked all CPM1-based parts, but for the MPC855 family this doesn't 
look right. The MPC855 has two 32-bit ports, port B and port E. Registers for 
port B are dir, par, odr and dat, and registers for port E are dir, par, sor, 
odr and dat.

You probably mean MPC885. Thanks for catching this, the 32bit registers really
are a mess on CPM1 platforms.

Are you working on a similar patch for the CPM2 ? CPM2 I/O ports are 32 bit 
wide and their registers are layed out like for port E on the MPC855. It 
should thus be possible to share code between CPM1 and CPM2.

Yes, some common port setup code could probably be moved to cpm.c.

Thanks,
Jochen
