+Subject: arm64: dts: marvell: armada-37xx: move firmware node to generic dtsi

+[ Upstream commit 3a52a48973b355b3aac5add92ef50650ae37c2bd ]
+
+Move the turris-mox-rwtm firmware node from Turris MOX' device tree into
+the generic armada-37xx.dtsi file and use the generic compatible string
+'marvell,armada-3700-rwtm-firmware' instead of the current one.
+
+Turris MOX DTS file contains also old compatible string for backward
+compatibility.
+
+The Turris MOX rWTM firmware can be used on any Armada 37xx device,
+giving them access to the rWTM hardware random number generator, which
+is otherwise unavailable.
+
+This change allows Linux to load the turris-mox-rwtm.ko module on these
+boards.
+
+Tested on ESPRESSObin v5 with both default Marvell WTMI firmware and
+CZ.NIC's firmware. With default WTMI firmware the turris-mox-rwtm fails
+to probe, while with CZ.NIC's firmware it registers the HW random number
+generator.

+
+Add more generic compatible string 'marvell,armada-3700-rwtm-firmware' for

+
+Current compatible string 'cznic,turris-mox-rwtm' is kept for backward
