via the Configuration Port, so restructure the code a little
to allow for them, and list at least one other system that does
(anything based on AMD Elan SC520).
XXX We don't actually check for Elan SC520 yet.
Use %lld instead and cast the args to (long long) explicitly.
I'm not sure about our policy vs. the C99 format string macros in
basesrc - should we use those here?
documentation:
- Remove "mainbus" altogether.
- The new root is "plb" - the Processor Local Bus.
- Attached to this is the "opb" - the On-chip Peripheral Bus, to which
all the on-chip devices are attached (except the cpu and pci host
bridge).
- Port-specific code can pass an array of 'struct plb_dev' to
config_rootfound() to attach extra devices to the plb. The walnut
port attaches a "pbus" (Peripheral Bus) in here for the RTC and
pc keyboard controller to attach to.
There is still much 405GP specific code; the next round of changes will
generalise this to enable easier support for other 4xx CPUs.
driver attaches where "pchb" would normally attach (it matches at a
higher match priority). The "elansc" driver currently provides support
for the watchdog timer built-in the SC520.
Thanks to Jasper Wallace for laying the ground-work for this (most
notably by providing a work-around for a watchdog-related bug in the
SC520).
to deal with aliasing of regular memory pages, because many processors don't
support it.
Now, the pmap marks all mappings of a page that has any non-equivalent
aliasing and any writable mapping, and the fault handlers watch for this
and flush other mappings out of the TLB and cache before (re)entering a
conflicting mapping.
When a page has non-equivalent aliasing, only one writable mapping at
a time may be in the TLB and cache. If no writable mapping is in the
TLB and cache, any number of read-only mappings may be.
The PA7100LC/PA7300LC fault handlers have not been converted yet.
EXCLUDE_UNENCRYPTED bit in the WI_RID_P2_ENCRYPTION value if we are
in shared key mode. Symbol cards, just to be different, supposedly
always want the EXCLUDE_UNENCRYPTED bit set (confirmed with the
Linux orinoco and spectrum24 drivers).
* Flesh out the Host-AP WEP transmit side. Note this does not yet
work properly; the frame as seen by the receiver FCS's incorrectly.
Both changes from OpenBSD. Not confirmed whether or not Host-AP WEP
works with OpenBSD (mail sent to millert).
