hi
i project use mpc8313
uboot printf

now
my memory space config :
0x0-0xfffffff is ddr space 256M CAN ACCESS
0x80000000-0x8fffffff is PCIMEM space 256M CAN ACCESS
0x90000000-0x9fffffff is PCIMEMIO space 256M CAN ACCESS
0xE0000000-0xEfffffff is IMMR NOR NAND space 256M CAN ACCESS

BUT else space can't access
ex
md 0xee000000
ee000000: ffffffff ffffffff ffffffff ffffffff

but

why?
how about it

Is related to the macro below
#define CFG_DBAT0L CFG_IBAT0L
#define CFG_DBAT0U CFG_IBAT0U
#define CFG_DBAT1L CFG_IBAT1L
#define CFG_DBAT1U CFG_IBAT1U

The addresses 0xd0000000 and 0xf0000000 are not defined in the memory map.

Please define LAWs configuration for these addresses.

Please define CONFIG_SYS_LBLAWBARx_PRELIM and CONFIG_SYS_LBLAWARx_PRELIM in include/configs/MPC8313ERDB.h in u-boot source code.
