From 325a22dc196a8738ba8389b8a4086345ff5e98db Mon Sep 17 00:00:00 2001 From: Ibai Erkiaga Date: Fri, 27 Sep 2019 11:37:04 +0100 Subject: [PATCH] arm64: zynqmp: probe firmware driver Probe ZynqMP firmware driver on the board initialization phase and ensure that firmware is in place to continue execution. The probing is done on board_init so it can be used for both SPL and U-Boot proper.
