[U-Boot] [PATCH v4 03/17] arm: socfpga: Move Stratix10 and Agilex reset manager common code
Ley Foon Tan

Thu Sep 12 10:10:51 UTC 2019
Move Stratix10 and Agilex reset manager common code to reset_manager_soc64.h.
Remove unused RSTMGR_XXX defines.
Signed-off-by: Ley Foon Tan <ley.foon.tan at intel.com>
---
v4:
- Change prefix from RSTMGR_S10* to RSTMGR_SOC64*.
v3:
- Add new reset_manager_soc64.h
- Convert to use defines instead of struct.
