Hello list,

inside the automatic U-Boot patch tracking system a new ticket
[DNX#2006110242000109] was created:

<snip>
> Tsi108 on chip pci controller support.
> 
> If there is no pci card, the tsi108/109 pci configure read will cause a
> machine check exception to the processor. PCI error should also be
> cleared after the read.
