I have tried to configure PortX for use of memory space 0x7000_0000. I have modified MCCR4[EXTROM] to enable entened ROM. but i can't accessed address 0x70000000 ... i find something worng in include/config_Sandpint8245.h according to define BATs in config_Sandpint8245.h not allocate BATs for address 0x7000000 , so i try change BAT1 for extended rom i modify ppcboot code to blow list

1. 0x40000000 used by initial stack , until sdram init....(BAT1 allocation) 2. command/board.c : board_init_r () this function use stack...in ram so no more need 0x40000000 3. my added code to BAT1 realloction for 0x70000000.. void move_bat1 (void) { mtspr (IBAT1L, (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)); mtspr (IBAT1U, (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP));

mtspr (DBAT1L, (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)); mtspr (DBAT1U, (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP)); __asm__ __volatile__("eieio"); __asm__ __volatile__("isync"); __asm__ __volatile__("sync");

}

4. call move_bat1 at board_init_r ......

but...board not working.....
