[coreboot] ASRock E350M1: Linux reports `piix4_smbus 0000:00:14.0: SMBus base address index region 0xcd6 already in use!`

[Paul Menzel]

Dear coreboot folks,


since [1]

        commit df729d7778a7e5878fac5545883f68e42372456a
        Author: Jens Rottmann <jrottm...@lippertembedded.de>

            AMD Fam14 boards: dimmSpd.c: Set `iobase` to `SMBUS0_BASE_ADDRESS` 
instead of `0xB00`

which I expanded to the ASRock E350M1, overlooking the new error
message, Linux complains about an already used base address index
region.

        calling  i2c_piix4_init+0x0/0x1000 [i2c_piix4] @ 559
        piix4_smbus 0000:00:14.0: SMBus base address index region 0xcd6 already 
in use!
        piix4_smbus: probe of 0000:00:14.0 failed with error -16

The address 0xb00 was used before and this should not have been changed
with the patch above. But it did. I looked through the code but could
not find where 0xcd6 comes from. Any pointers would be very much
appreciated.


Thanks,

Paul
