Hi,

We  are using MPC885ADS Eval. board ,we are porting  U-Boot 1.1.1on it and working fine,
but we have following query

1. When we trying to change serial port from SMC1 to SMC2  by
  defining following in "MPC885ADS.h" :

	#define	CONFIG_8xx_CONS_SMC2	1	/* Console is on SMC2 */
	#undef	CONFIG_8xx_CONS_SMC1
	#undef	CONFIG_8xx_CONS_NONE	
we are not getting anything  on serial console.

2.  We are getting  8 Mbyte of Flash memory SIMM - theRPCF08324NE5BSSG-70 by RPC , which
internally composed of 16  AM29F040 devices. We are able to configure 2 MB Flash memory 
and working fine. 
But when we are trying to configure for 8MB  by changinf  following in "/board/fads/flash.c : flash_get_size()"

info->sector_count = 32;
info->size = 0x00800000;
 
instead of 
 
 info->sector_count = 8;
info->size = 0x00200000;

It gives some error as below :


CPU:   MPC885ZPnn at 120 MHz: 8 kB I-Cache 8 kB D-Cache FEC present
Board: MPC885ADS rev NR
DRAM:  (8 MB SDRAM)  8 MB
