Since the Pfuze initializations are similar on various mx6 SABRE boards. Factorize the initialization to a common function in file board/freescale/common/pfuze.c. So that all SABRE boards BSP can share the function. Signed-off-by: Ye.Li <B37916@freescale.com> --- Changes since v1: - Factorize the pfuze init function for sabre boards Changes since v2: - Replace the magic value to definitions in pfuze driver. board/freescale/common/Makefile | 1 + board/freescale/common/pfuze.c | 54 +++++++++++++++++++++++++++++++++++++++ board/freescale/common/pfuze.h | 12 ++++++++ 3 files changed, 67 insertions(+), 0 deletions(-) create mode 100644 board/freescale/common/pfuze.c create mode 100644 board/freescale/common/pfuze.h
