What's next?

Hi,

I am still having problems scanning the noncoherent chains connected to
CPU1-3 of the motherboard I am working to support. I could temporarily
work around this issue by setting the Config Base and Limit registers of
those links to 0. Otherwise collapsing the chain when setting up that
CPU fails. I set the Config Base and Limit registers like this:
        PCI_ADDR(0, 0x18, 1, 0xE0), 0x0000FC88, 0x04000103,
        PCI_ADDR(0, 0x18, 1, 0xE4), 0x0000FC88, 0xff050213,
since there's bus 0-4 on cpu0 when i don't scan cpu1

Looking at incoherent_ht.c there are two functions that are very
similar:

static int ht_setup_chain(device_t udev, unsigned upos)
static int ht_setup_chains(const struct ht_chain *ht_c, int ht_c_num)

the first one warns:
#warning "FIXME handle multiple chains!"

Should we not drop ht_setup_chain in favour of ht_setup_chains?

Also later on it dies apparently in amdk8_scan_chains in
northbridge/amd/amdk8/northbridge.c.

Something is severely wrong with my link setup, but I double checked
where the coherent and non coherent links hang off of..

Pointers?

Stefan.
