This makes building the actual object files optional to the selected mode, which saves users who know which kind of USB mode support they need some binary size. Unimplemented functions are stubbed out with static inline functions.

Say Y here if your system has a dual role high speed USB
|
|
controller based on the Mentor Graphics silicon IP. Then
|
|
configure options to match your silicon and the board
|
|
it's being used with, including the USB peripheral role,
|
|
or the USB host role, or both.
|
|
|
|
Texas Instruments families using this IP include DaVinci
|
|
(35x, 644x ...), OMAP 243x, OMAP 3, and TUSB 6010.
|
|
|
|
Analog Devices parts using this IP include Blackfin BF54x,
|
|
BF525 and BF527.
|
|
|
|
If you do not know what this is, please say N.
|
|
|
|
To compile this driver as a module, choose M here; the
|
|
module will be called "musb-hdrc".

All data is copied between memory and FIFO by the CPU.

DMA controllers are ignored.

Do not choose this unless DMA support for your SOC or board
|
|
is unavailable (or unstable). When DMA is enabled at compile time,
|
|
you can still disable it at run time using the "use_dma=n" module
|
|
parameter.
