[U-Boot] [PATCH v2 26/30] arm: socfpga: arria10: Added miscellaneous drivers for Arria 10

Chee Tien Fong
2016-12-28T06:34:37Z

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.
