[PATCH v1 08/22] arm: socfpga: Restructure Stratix10 and Agilex handoff code
Siew Chin Lim

Tue Sep 22 11:49:16 CEST 2020
Restructure Stratix10 and Agilex handoff code to used by
all SOC64 devices, in preparation to support handoff for
Diamond Mesa.
Remove wrap_pinmux_config_s10.c. Add wrap_handoff_soc64.c
which contains the generic function to parse the handoff
data.
Update system_manager_soc64.c to use generic handoff
function in wrap_handoff_soc64.c.
