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

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
