From a0ffee6b145933f411b1c33daa2cdd54e77b2b15 Mon Sep 17 00:00:00 2001 From: Luca Fancellu Date: Wed, 13 Oct 2021 15:52:02 +0100 Subject: [PATCH] arm/docs: Clarify legacy DT bindings on UEFI MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since the introduction of UEFI boot for Xen, the legacy compatible strings were not supported and the stub code was checking only the presence of “multiboot,module” to require the Xen UEFI configuration file or not. The documentation was not updated to specify that behavior. Add a phrase to docs/misc/arm/device-tree/booting.txt to clarify it.
