The datasheet says 2KB FIFO, but accroding to many
code examples, the F1C100s has at least 4KB of FIFO memory.
This is working with cdc_msc example,
but I'm not sure, this should be checked.
Allwinner F1Cx00s family is a series of SoCs
with Mentor MUSB controller and HS phy. It comes
with a slightly different register space layout,
and some quirks, so it's not multiplexed with
the existing musb support library.
This library currently requires to be compiled
