Sorry just noticed this going through my inbox.. Please let me know
if there are other pending build errors I may have missed.

The patch below should fix this, I don't have any blackfin
machines or compilers here to test with though.

Subject: [PATCH] usb: musb: Fix tusb6010 compile error on blackfin

We have CONFIG_BLACKFIN ifdef redefining all musb registers in
musb_regs.h and tusb6010.h is never included causing a build
error with blackfin-allmodconfig and COMPILE_TEST.

Let's fix the issue by not building tusb6010 if CONFIG_BLACKFIN
is selected.
