From 365d88ac7ef562daedded3dacb922bd92ccc72cc Mon Sep 17 00:00:00 2001 From: Oleksandr Andrushchenko Date: Thu, 6 Aug 2020 12:42:46 +0300 Subject: xen: Add essential and required interface headers Add essential and required Xen interface headers only taken from the stable Linux kernel stable/linux-5.7.y at commit 66dfe4522160 Linux 5.7.5. These are better suited for U-boot than the original headers from Xen as they are the stripped versions of the same. At the same time use public protocols from Xen RELEASE-4.13.1, at commit 6278553325a9 update Xen version to 4.13.1 as those have more comments in them.
