[U-Boot] MPC8377: SVR wrong ?

[André Schwarz]

Kim, Timur,

after spending some more hours there's some success in MPC8377 based
board bring up.

After using I2C for HRCW boot sequencing it is working fine now.
BDI setup is also up and running, i.e. DDR and Flash are working fine.

U-Boot is starting properly and hangs after relocation, but having a
look at the relocated address in RAM everything looks fine.
Having a look at the DDR-Bus it is working fine and signal integrity is
quite good.


What worries me is that the CPU doesn't get recognized properly :

The BGA package shows "MPC8377CVRALG" ... which is what we've ordered.

After looking at the Manual I'd expect SVR = 80C7_0021


Unfortunately BDI tells "SVR is 0x80C30021" indicating a MPC8379 :-(

U-Boot comes up with :
CPU:   e300c4, MPC8379, Rev: 2.1 at ...


Of course this would lead to disaster regarding PCIe/SATA port config
since they're different. I have configured my board with 2x PCIe + 2x
SATA ....


Any ideas ?


Regards,
André
