[U-Boot-Users] Why is BR2/OR2 disabled for CONFIG_MPC85xx?

[Gerhard Jaeger]

Hi list,

while adding support for a custom MPC8540 board, I found the following stuff in
cpu/mpc85xx/cpu_init.c:

#if !defined(CONFIG_MPC85xx)
#if defined(CFG_BR2_PRELIM) && defined(CFG_OR2_PRELIM)
	memctl->or2 = CFG_OR2_PRELIM;
	memctl->br2 = CFG_BR2_PRELIM;
#endif
#endif

Could anybody shed some light on that? It's not clear to me why 
these two registers should not be written too, when we have a
i.e. 8540 design...

Thanx in advance
Gerhard
