Hi fulinux

seems you used wrong uboot, please try to build from i.MX6 product page

Board Support Packages (38)

i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo and i.MX 6Sololite Linux

BSP Source Code Files (REV L3.0.35_4.1.0)

http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/i.mx-applications-processors/i.mx-6-processors/i.mx6qp/sabre-board-for-smart-devices-reference-design-based-on-the-i.mx-6-series:RDIMX6SABREBRD?fpsp=1&tab=Design_Tools_Tab

or from

Index of /buildsources/u/u-boot/u-boot-2009.08

and use Chapter 1 Porting U-Boot attached Porting Guide.
