does coreboot support kvm & WPCE775x & other questions

[dhan.war]

hi all

i am using toshiba satellite c850d-m5010. the kvm is disabled by default 
in BIOS. it seems to me that many laptop manufacturers does not fully 
support kvm.

my output of the superiotool :
# superiotool
superiotool r6637
Found Nuvoton WPCE775x / NPCE781x (id=0x00, rev=0x01) at 0x2e

i did a search on website & it points to me 2 links only [[a] & [b]].
the link [a] is silent about BIOS & CB.
the link [b] is silent about datasheets & comment.

the output of superiotool -V also states that dump is available.

there is also a request to add WPCE775x on mailing list [c] & there 
seems to no answer to the thread.

my questions:
[1] does coreboot support kvm ?
[2] can i install coreboot on Nuvoton WPCE775x / NPCE781x ?
[3] does the support for Nuvoton WPCE775x / NPCE781x is added in coreboot ?
[4] what does the dump available mean in output of superiotool -V ?

if you need any further information please let me know. please also 
provide appropriate commands if it involves any packages.

thank you reading the message patiently. even though i am subscribed to 
mailing list, please always cc me.

Hello!
Can you enable the KVM functions?
 Part of the problem with laptops is that there is a thing on them
called an Embedded Controller, EC for short. Those devices do all of
the housekeeping chores that the main system has delegated to them.
For example certain functions are on it.

To that end most laptops aren't supported because these devices are
proprietary in their designs and the programing of them.

I think this is more a question for SeaBIOS (http://www.seabios.org/SeaBIOS)
?

[2] can i install coreboot on Nuvoton WPCE775x / NPCE781x ?

The question is whether or not you can install coreboot on the Toshiba
c850d-m5010. I see that it uses an AMD E-series APU -- That may actually be
supported to some extent in coreboot. However, there is a lot more work
that is needed to fully support a mainboard, and laptops can be difficult
to work with.

Although this EC is not currently used in any platforms which coreboot
supports, IIRC it uses standard ACPI and PnP interfaces for most of its
functionality.

As Vladimir points out, the EC should be of marginal importance to coreboot.

It is simply a listing of register values.
