[U-Boot-Users] Custom MPC8347 Board can't access cache

Hello All,

I am trying to bring up a custom MPC8347 board with source based off of
1.3-rc1, unfortunately, I am not making it to board_init_f.

Using an abatron bdi, I've discovered the offending instruction is on
cpu/mpc83xx/start.S:752 - 

752    mtmsr r5   /* r5 is 0x3072 */

Has anyone else seen this issue?

For reference, here are some configuration settings that may be of
value:

#define CFG_INIT_RAM_ADDR  0x20000000  /* Initial RAM address */
#define CFG_INIT_RAM_END   0x1000      /* End of used area in RAM*/
#define CFG_IBAT2L   (CFG_INIT_RAM_ADDR | BATL_PP_10 |
BATL_MEMCOHERENCE)
#define CFG_IBAT2U   (CFG_INIT_RAM_ADDR | BATU_BL_128K | BATU_VS |
BATU_VP)

Does anyone have any insight? Thanks for the help,
Sam Sparks
