I just compiled 2.6.38-rc1 and it doesn't fail for me.

There's a bug on your .config, did you edit by hand ? AM35X doesn't have
DMA support as of today, that's why we have:
config MUSB_PIO_ONLY
bool 'Disable DMA (always use PIO)'
depends on USB_MUSB_HDRC
default USB_MUSB_TUSB6010 || USB_MUSB_DA8XX || USB_MUSB_AM35X
did you disable PIO only ? I know that's a bit fuzzy still, a few
patches will be needed to clean up the entire MUSB Kconfig, I apologize
for that.
