New subject: [U-Boot] [v4 24/29] arm: socfpga: arria10: Added drivers for Arria10 Reset Manager

From: Tien Fong Chee tien.fong.chee@intel.com

Drivers for reset manager is restructured such that common functions, gen5 drivers and Arria10 drivers are moved to reset_manager.c, reset_manager_gen5.c and reset_manager_arria10.c respectively.

New subject: [U-Boot] [v4 25/29] arm: socfpga: arria10: Added miscellaneous drivers for Arria 10

From: Tien Fong Chee tien.fong.chee@intel.com

The drivers is restructured such common functions, gen5 functions. and arria10 functions are moved to misc.c, misc_gen5 and misc_arria10 respectively.

New subject: [U-Boot] [v4 26/29] arm: socfpga: arria10: Added drivers for Arria10 clock manager

From: Tien Fong Chee tien.fong.chee@intel.com

The drivers is restructured such common functions, gen5 functions, and arria10 functions are moved to clock_manager.c, clock_manager_gen5 and clock_manager_arria10 respectively.
