To my opinion platforms/82xx/m8260_setup.c is more relevant than in
syslib. This is not a vital requirement though, I just want to know
whether someone considers the same.

OK. These stuff is not there yet because I wasn't sure what should come
first - the platform stuff or driver that will utilize it. So, the
correct way is to define PD first, than add drivers.

Because I want only partnum & masknum (RM, Fig. 4.26), remaining part is
HRCW-dependent and can be written so couldn't be used as a device
identification.

What exactly do you mean by this? Enumerate all the 82xx boards in
mpc82xx_sys.c identifying them by immr, or?

Agreed.
