[U-Boot] [PATCH v3 4/5] imx: mx6sxsabresd: Use the pfuze common init function

Thu Nov 6 09:29:01 CET 2014


Modify the pfuze init for mx6sxsabresd to use the shared
"pfuze_common_init" function. And move this initialization to
power_init_board.

Changes since v1:
- Change to use pfuze common init function for sabre boards.

Changes since v2:
- Move the pfuze init to power_init_board
