Hi,

Why do you think you have to do this? This is _NOT_ necessary.
parameters of the asm to get the HRESET_N pulse. So this is the version
which works (on a MPC823e) in the context of the Linux kernel:
/* Get base address mapped by BR0/OR0 and map it in */
val = ((immap_t *)IMAP_ADDR)->im_memctl.memc_br0 & 0xFFFF8000;
val = (int) ioremap( retval, 0x4000 );
This code is wrong. You clobber the value of "val" here.
