Mainline kernel on mx28evk

I'm trying to use mainline kernel on mx28evk.

The kernel boots by following this guide:


However there is no USB support and I can not enable USB support in the kernel menuconfig.

USB supported by fsl-ehci, which is CONFIG_USB_EHCI_FSL. The main problem is this option is not available in menuconfig for MXS platform. Even EHCI HCD (USB 2.0) support is not available at all. These options are hidden for mx28evk.


Has anyone got an idea how to make USB work in mainline kernel? Or maybe you already have compiled mainline kernel with all supported devices for mx28evk. 

Kernel I'm trying to run: 3.3.4 , 3.4.0-rc6 (both with same results)
