sorry - thought it was clear already.

CPU:   e300c4, MPC8379, Rev: 2.1 at 600 MHz, CSB: 400 MHz

- Boot from NOR Flash
- HRCW from I2C EEPROM
- Reset Vector 0x100, i.e. low boot.

Initial RAM ...

#define CONFIG_SYS_INIT_RAM_LOCK       1
#define CONFIG_SYS_INIT_RAM_ADDR       0xE6000000
#define CONFIG_SYS_INIT_RAM_SIZE        0x1000
#define CONFIG_SYS_GBL_DATA_SIZE        0x100
#define CONFIG_SYS_GBL_DATA_OFFSET  (CONFIG_SYS_INIT_RAM_SIZE - 
CONFIG_SYS_GBL_DATA_SIZE)

... mapped by BAT5

#define CONFIG_SYS_IBAT5L       (CONFIG_SYS_INIT_RAM_ADDR | BATL_PP_10)
#define CONFIG_SYS_IBAT5U       (CONFIG_SYS_INIT_RAM_ADDR | BATU_BL_128K 
| BATU_VS | BATU_VP)
#define CONFIG_SYS_DBAT5L       CONFIG_SYS_IBAT5L
#define CONFIG_SYS_DBAT5U       CONFIG_SYS_IBAT5U


Of course ELDK-4.2 toolchain.

If it's an alignment or linking problem it could have the same root cause.
Just want to give as much information as I can.
