[U-Boot] [PATCH v5 03/19] arm: socfpga: Move Stratix10 and Agilex reset manager common code

Fri Oct 11 09:52:06 UTC 2019


Move Stratix10 and Agilex reset manager common code to
reset_manager_soc64.h. Changed macros to RSTMGR_SOC64_*.

Remove unused RSTMGR_XXX defines.

---
v5:
- Remove reset_manager_s10.h and use reset_manager_soc64.h directly.

v4:
- Change prefix from RSTMGR_S10* to RSTMGR_SOC64*.

v3:
- Add new reset_manager_soc64.h
- Convert to use defines instead of struct.
