From 7171d9929640fad7d0176f6fbb16263e2d8d1559 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay <patrick.delaunay@foss.st.com> Date: Wed, 1 Jun 2022 18:33:40 +0200 Subject: stm32mp: stpmic1: remove the debug unit request by debugger Depending on backup register value, U-Boot SPL maintains the debug unit powered-on for debugging purpose; only BUCK1 is required for powering the debug unit, so revert the setting for all the other power lanes, except BUCK3 that has to be always on. To be functional this patch requires a modification in the debugger ,openocd for example, to update the STM32MP15 backup register when it is required to debug SPL after reset. After deeper analysis this behavior will be never supported in tools so the associated code, will be never used and the associated code can be removed.
