Hi,
I'm porting Linux Kermel 2.6.27 for our custom board. Currenlly I have
some troubles with the SATA (SIL3114) controller. The controller and
hard disk are found, but when the driver try to read the partiton table,
error messages (timeouts) appears (see attachment).
Can somebody please give me a tip, where the problem can possible be.
Are there some resources in Internet, which describes init process of an
PCI-Bridge resp. PCI-Device under Linux?
In attachment are the log-output from boot-process and the corresponding
dts files.
Best regards
Eduard Fuchs
