We have a MPC7410 based board and we are trying to port Linux on the same.
the Board Architecture/UART connection is as follows
*MPC7410 ---> MPC107(PCI Bridge) ---> PLX9052(PCI->Local Bus Bridge) --->
The address mapping is as follows
PLX9052 @ 0xDB00_0000
UART @ 0xDB00_0100
FLASH @ 0xFF00_0000
RAM @ 0x0
We have to port Linux 2.6.24( default one with ELDK4.2).
as we don't have a debugger, we are using (my_reset) function which simply
resets the board.
We have uboot up and running. we are downloading uImage to RAM location
@0x800000 and JMP to 0x80000
Linux is executing till setup_arch() call in the start_kernel() function.
We are facing some issue in page_init() call; also on setting the BAT
registers.(which is done at platform_init)
Anyone got any clue how to set the BAT for MPC7410 ?
