        src/sys/dev/pci: satalink.c

Log Message:
When the Silicon Image 3112 retries a PCI memory read command, it
may retry it as a memory read multiple command under some circumstances.
This can totally confuse some PCI controllers, so ensure that it
will never do this by making sure that the Read Threshold (FIFO
Read Request Control) field of the FIFO Valid Byte Count and Control
registers for both channels (BA5 offset 0x40 and 0x44) are set to
be at least as large as the cacheline size register (the unit of
measure for these registers is 32 bytes).
