[MINI-OS PATCH v2] add config support for each Xen library
Posted by Juergen Gross 2 months, 1 week ago 
Instead of adding all or no Xen library (controlled by CONFIG_XC),
support a dedicated config option for each library instead,
defaulting to disabled.

As it is no longer needed now, drop the CONFIG_XC support.

V2:
- merge patches of the V1 series (Samuel Thibault)

Note: do not apply to the tree until the related Xen series
"stubdom: prepare more fine grained Xen library usage" has been
applied.

And at this point it's solely "stubdom: add fine grained library config
items to Mini-OS configs" which is left as a dependency, isn't it?

Yes.

In theory the Mini-OS patch could be applied already, as long as Config.mk
on the Xen side isn't updated with the new Mini-OS commit id, but I think
we should wait nevertheless.

"libraries".

But better grammar would be "Instead of Xen libraries being all or none
(..."

Can fix on commit.
